  • How to change the value of progressbar in C#?

    - by shekhar
    Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,

  • IE7 Negative value cuts off half the element - bug?

    - by Yammi
    I've relatively positioned one of the elements with negative 'top' and 'left' values, the negative 'left' value actually takes the element outside of the 'body' width, this seems fine in all browsers apart from IE7 where it just cuts it off. establi.sh I thought it might be that weird bug where if it's outside the parent container then you have to set a z-index but that didn't work, then I thought it might be the hasLayout bug but trying to fix that didn't work. I'm not an expert on IE browsers so need some help. I'm thinking IE7 might be choking as the negative left value actually takes it outside the body? Thanks

  • Is there a way to set the value of $? in a mock in Ruby?

    - by rleber
    I am testing some scripts that interface with system commands. Their logic depends on the return code of the system commands, i.e. the value of $?. So, as a simplified example, the script might say: def foo(command) output=`#{command}` if $?==0 'succeeded' else 'failed' end end In order to be able to test these methods properly, I would like to be able to stub out the Kernel backquote call, and set $? to an arbitrary value, to see if I get appropriate behavior from the logic in the method after the backquote call. I can't figure out a way to do this. (In case it matters, I'm testing using Test::Unit and Mocha.)

  • Is it possible to inspect the contents of a Table Value Parameter via the debugger?

    - by Stephen Edmonds
    Does anyone know if it is possible to use the Visual Studio / SQL Server Management Studio debugger to inspect the contents of a Table Value Parameter passed to a stored procedure? To give a trivial example: CREATE TYPE [dbo].[ControllerId] AS TABLE( [id] [nvarchar](max) NOT NULL ) GO CREATE PROCEDURE [dbo].[test] @controllerData [dbo].[ControllerId] READONLY AS BEGIN SELECT COUNT(*) FROM @controllerData; END DECLARE @SampleData as [dbo].[ControllerId]; INSERT INTO @SampleData ([id]) VALUES ('test'), ('test2'); exec [dbo].[test] @SampleData; Using the above with a break point on the exec statement, I am able to step into the stored procedure without any trouble. The debugger shows that the @controllerData local has a value of '(table)' but I have not found any tool that would allow me to actual view the rows that make up that table.

  • Does a CPU assigns a value atomically to memory?

    - by Poni
    Hi! A quick question I've been wondering about for some time; Does the CPU assign values atomically, or, is it bit by bit (say for example a 32bit integer). If it's bit by bit, could another thread accessing this exact location get a "part" of the to-be-assigned value? Think of this: I have two threads and one shared "unsigned int" variable (call it "g_uiVal"). Both threads loop. On is printing "g_uiVal" with printf("%u\n", g_uiVal). The second just increase this number. Will the printing thread ever print something that is totally not or part of "g_uiVal"'s value? In code: unsigned int g_uiVal; void thread_writer() { g_uiVal++; } void thread_reader() { while(1) printf("%u\n", g_uiVal); }

  • c# converting select case VBA to c# SWITCH

    - by herrow
    i have some vba code that i need to convert to c# Select Case letter0 Case "A01" Cells(rownum, 2).Value = "1" Case "B01" Cells(rownum, 2).Value = "2" Case "C01" Cells(rownum, 2).Value = "3" Case "D01" Cells(rownum, 2).Value = "4" Case "E01" Cells(rownum, 2).Value = "5" Case "F01" Cells(rownum, 2).Value = "6" Case "G01" Cells(rownum, 2).Value = "7" Case "H01" Cells(rownum, 2).Value = "8" Case "A02" Cells(rownum, 2).Value = "9" Case "B02" ... .. i understand how to do a switch on this, but is there an easier method? i will not be checking CELLS(rownum.........) instead of will be doing switch(somestring) is there an easier way to do this than explicitly write every single case?

  • Will Sytem.currentTimeMillis always return a value >= previous calls?

    - by 1984isnotamanual
    http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis() says: Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. It is not clear to me if I am guaranteed that this code will always print ever increasing (or the same) numbers. while (1) { System.out.println(System.currentTimeMillis() ); }

  • Get URL parameter function that gets value of url part or returns true if it's there but with no val

    - by LLer
    I'm using the following function to get a URL parameter. function gup(name, url) { name = name.replace(/[\[]/, '\\\[').replace(/[\]]/, '\\\]'); var results = new RegExp('[\\?&]'+name+'=?([^&#]*)').exec(url || window.location.href); return results == null ? null : results[1]; } It works only if the parameter has a value, for example. gup('a', 'http://example.com/page.php?a=1&b=2'); will return 1. But if I try gup('a', 'http://example.com/page.php?a&b=2'); It returns null. I want it to return true because parameter "a" exists in that url, even though it has no value it's still there and gup() should return true. Could I get a bit of help rewriting this? I'm not that good with regex.

  • Setting a form field's valule during validation

    - by LaundroMat
    Hi, I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method). Thanks in advance!

  • SQL SERVER – Introduction to Extended Events – Finding Long Running Queries

    - by pinaldave
    The job of an SQL Consultant is very interesting as always. The month before, I was busy doing query optimization and performance tuning projects for our clients, and this month, I am busy delivering my performance in Microsoft SQL Server 2005/2008 Query Optimization and & Performance Tuning Course. I recently read white paper about Extended Event by SQL Server MVP Jonathan Kehayias. You can read the white paper here: Using SQL Server 2008 Extended Events. I also read another appealing chapter by Jonathan in the book, SQLAuthority Book Review – Professional SQL Server 2008 Internals and Troubleshooting. After reading these excellent notes by Jonathan, I decided to upgrade my course and include Extended Event as one of the modules. This week, I have delivered Extended Events session two times and attendees really liked the said course. They really think Extended Events is one of the most powerful tools available. Extended Events can do many things. I suggest that you read the white paper I mentioned to learn more about this tool. Instead of writing a long theory, I am going to write a very quick script for Extended Events. This event session captures all the longest running queries ever since the event session was started. One of the many advantages of the Extended Events is that it can be configured very easily and it is a robust method to collect necessary information in terms of troubleshooting. There are many targets where you can store the information, which include XML file target, which I really like. In the following Events, we are writing the details of the event at two locations: 1) Ringer Buffer; and 2) XML file. It is not necessary to write at both places, either of the two will do. -- Extended Event for finding *long running query* IF EXISTS(SELECT * FROM sys.server_event_sessions WHERE name='LongRunningQuery') DROP EVENT SESSION LongRunningQuery ON SERVER GO -- Create Event CREATE EVENT SESSION LongRunningQuery ON SERVER -- Add event to capture event ADD EVENT sqlserver.sql_statement_completed ( -- Add action - event property ACTION (sqlserver.sql_text, sqlserver.tsql_stack) -- Predicate - time 1000 milisecond WHERE sqlserver.sql_statement_completed.duration > 1000 ) -- Add target for capturing the data - XML File ADD TARGET package0.asynchronous_file_target( SET filename='c:\LongRunningQuery.xet', metadatafile='c:\LongRunningQuery.xem'), -- Add target for capturing the data - Ring Bugger ADD TARGET package0.ring_buffer (SET max_memory = 4096) WITH (max_dispatch_latency = 1 seconds) GO -- Enable Event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=START GO -- Run long query (longer than 1000 ms) SELECT * FROM AdventureWorks.Sales.SalesOrderDetail ORDER BY UnitPriceDiscount DESC GO -- Stop the event ALTER EVENT SESSION LongRunningQuery ON SERVER STATE=STOP GO -- Read the data from Ring Buffer SELECT CAST(dt.target_data AS XML) AS xmlLockData FROM sys.dm_xe_session_targets dt JOIN sys.dm_xe_sessions ds ON ds.Address = dt.event_session_address JOIN sys.server_event_sessions ss ON ds.Name = ss.Name WHERE dt.target_name = 'ring_buffer' AND ds.Name = 'LongRunningQuery' GO -- Read the data from XML File SELECT event_data_XML.value('(event/data[1])[1]','VARCHAR(100)') AS Database_ID, event_data_XML.value('(event/data[2])[1]','INT') AS OBJECT_ID, event_data_XML.value('(event/data[3])[1]','INT') AS object_type, event_data_XML.value('(event/data[4])[1]','INT') AS cpu, event_data_XML.value('(event/data[5])[1]','INT') AS duration, event_data_XML.value('(event/data[6])[1]','INT') AS reads, event_data_XML.value('(event/data[7])[1]','INT') AS writes, event_data_XML.value('(event/action[1])[1]','VARCHAR(512)') AS sql_text, event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS tsql_stack, CAST(event_data_XML.value('(event/action[2])[1]','VARCHAR(512)') AS XML).value('(frame/@handle)[1]','VARCHAR(50)') AS handle FROM ( SELECT CAST(event_data AS XML) event_data_XML, * FROM sys.fn_xe_file_target_read_file ('c:\LongRunningQuery*.xet', 'c:\LongRunningQuery*.xem', NULL, NULL)) T GO -- Clean up. Drop the event DROP EVENT SESSION LongRunningQuery ON SERVER GO Just run the above query, afterwards you will find following result set. This result set contains the query that was running over 1000 ms. In our example, I used the XML file, and it does not reset when SQL services or computers restarts (if you are using DMV, it will reset when SQL services restarts). This event session can be very helpful for troubleshooting. Let me know if you want me to write more about Extended Events. I am totally fascinated with this feature, so I’m planning to acquire more knowledge about it so I can determine its other usages.

  • Your Day-by-Day Guide to Agile PLM at Oracle OpenWorld 2012

    - by Kerrie Foy
    This year’s Oracle OpenWorld conference is nearly here, and we’re all excited about what we have planned! With five days of activities and customer presenters from market leaders and top innovators like The Coca-Cola Company, Starbucks, JDSU, Facebook, GlobalFoundries, and more, this is an event you don't want to miss. I've compiled this day-by-day guide to help anyone keep track of all the “Product Lifecycle Management and Product Value Chain” sessions and activities at OpenWorld 2012, September 30 – October 4 in San Francisco, California.  Monday, October 1 There are great networking activities on Sunday September 30, but PLM specific sessions start after general conference keynotes on Monday, October 1 at 10:45 a.m. at the InterContinental Hotel in room Telegraph Hill. In fact, most of our sessions this year will be held in this room, which is still close to the conference keynotes in Moscone, but just far enough away to allow some focused networking and discussions.   This first session, 10:45 – 11:45 a.m. is a joint session with the Agile and AutoVue teams, entitled “Streamline PLM Design-to-Manufacturing Processes with AutoVue Visualization Soltuions” featuring presenters from Oracle as well as joint AutoVue and Agile PLM customer GlobalFoundries. In the following 12:15 – 1:15 p.m. slot, there are two sessions to choose from, so if you have a team of representatives attending OpenWorld, you may consider splitting up to catch both of these: a) Our General Session will be held in the InterContinental Hotel Ballroom C, which will cover our complete enterprise PLM strategy, product updates, and roadmaps. It’s our pleasure to feature a customer keynote presentation from Chris Bedi, CIO, and Rajeev Sethi, Director IT Business Engagement, of JDSU. b) A focused session on integrating PLM with Engineering and Supply Chain Systems will be held on the second floor of Moscone West (next to the InterContinental) in room 2022. Join to discover how these types of integrations help companies manage common and integrated design information across all MCAD, ECAD, and software components. After a lunch break and perhaps a visit to the Demogrounds in Moscone West, select from two product roadmap sessions in the next time slot (3:15 – 4:15 p.m.): an Agile 9.3.x session located in the InterContinental’s Ballroom C, and an Agile PLM for Process session located back in the InterContinental’s Telegraph Room. Both sessions will have strong content around each product line’s latest releases, vision, and customer examples. We are very pleased to feature Daniel Soosai of Facebook in the A9 session and Vinnie D’Agostino of The Coca-Cola Company in the PLM for Process session. Afterwards, hang in there for one last session of the day from 4:45 – 5:45 p.m.; it’s an insightful discussion on leveraging Agile PLM as the Foundation for Enterprise Quality Management, and it’s sure to be one of the best. In the Telegraph Room, this session will feature Oracle experts, partner co-presenter David Bartlett from CPG Solutions, and customer co-presenter Thomas Crowe, CIO of PL Developments. Hear their experience around implementing collaborative, integrated solutions to ensure effective knowledge transfer throughout an organization, and how to perform analysis in real time to resolve product quality issues swiftly and efficiently. On Monday evening there will be plenty of industry, product, and partner dinners, so take advantage of all the networking opportunities and catch some great tunes at the 5 day Oracle OpenWorld Music Festival! Tuesday, October 2 Tuesday starts early with a special PLM Networking Brunch, sponsored by several partners, from 8:30 a.m. – 10:30 a.m. at the B Restaurant that sits atop Yerba Buena Gardens. You’ll have the unique opportunity to meet with like-minded industry peers and a PLM partner to discuss a topic of your choosing while enjoying a delicious meal. Registration is required, so to inquire about attending this brunch, please email Terri.Hiskey-AT-oracle.com. After wrapping up your conversations over brunch, head over to the Marriott Marquis in the Nob Hill CD room for a chance to experience the Oracle Product Lifecycle Analytics solution in a Hands-On Lab, open from 10:15 a.m. – 12:45 p.m. Experts will be there to answer your questions. Back in the InterContinental Hotel’s Telegraph room, the session on “Ideation and Requirements Management: Capturing the Voice of the Customer” begins at 11:45 a.m. – 12:45 p.m. This may be the session for you if you’re struggling with challenges like too many repositories of customer needs, requests, and ideas; limited visibility into which ideas are being advanced by customers and field resources; or if you’re unable to leverage internal expertise to expose effort and potential risks. This session will discuss how Agile PLM can help you overcome ideation challenges to deliver the right products to their targeted markets and fulfill customer desires. Next, from 1:15 – 2:15 p.m. join us for a session on Managing Profitable Innovation with Oracle Product Lifecycle Analytics. If you missed the Hands-on Lab, have more questions, or simply want to be inspired by the product’s forward-thinking vision and capabilities, this is a great opportunity to meet the progressive-minded executives behind the application. After this session, it may be a good opportunity to swing by the Demogrounds in Moscone West and visit the Agile PLM demos at exhibit booths #81 for Agile PLM for Discrete Manufacturing, #70 for Agile PLM for Process, and #82 for AutoVue and Agile PLM Enterprise Visualization. Check out the related Supply Chain Management booths close by if you’re interested - here's the map. There’s always lots to see and do around the exhibit area. But don’t forget the last session of the day from 5:00 p.m. – 6:00 p.m. in Telegraph Hill on Managing Product Innovation and Compliance in Life Science Companies, a “must-see” if you’re in this industry. Launching innovative products quickly is already a high-stakes challenge, but companies in the life sciences industry face uniquely severe consequences when new products don’t perform or comply as required. In recent years, more and more regulations have become mandatory, and new ones, such as REACH, are currently going into effect for several companies. Customer presenters from pharmaceutical leader Eli Lilly will share how they’ve leveraged Agile PLM to deliver high-quality, innovative products in a fast-paced, heavily regulated market environment. Tuesday evening unwind at the Supply Chain Management Reception from 6:00 – 8:00 p.m. at the premier boutique Roe Nightclub and Lounge, which is located about three blocks down on Howard Street (on the other side of Moscone from the InterContinental Hotel). Registration is required. Click here for the details.   Wednesday, October 3 We have another full line-up on Wednesday, so be ready for an action-packed day. We start with a session at 10:15 – 11:15 a.m. in the Telegraph Room where we have a session on “PLM for Consumer Products: Building an Engine for Quality and Innovation” with featured presenters from Starbucks and partner Kalypso. This is a rare opportunity to learn directly from Starbucks how they instill quality and innovation throughout their organization, products, and processes, leveraging PLM disciplines with strong support from their partner.  If you’re not in the consumer products industry, we recommend attending another session at 10:15 – 11:15 a.m. in Moscone West room 3005: “Eco-Enterprise Innovation Awards and the Business Case for Sustainability” featuring Jeff Henley, Oracle’s Chairman of the Board and Jon Chorley, Chief Sustainability Officer. Oracle will honor select customers with Oracle’s Eco-Enterprise Innovation award, which recognizes customers and their respective partners who rely on Oracle products to support their green business practices to reduce their environmental impact while improving business efficiencies and reducing costs. The awards presentation is followed by a panel discussion with customers and Oracle executives, who describe how these award-winning organizations are embracing environmental initiatives as a central part of their business strategy and how information technology plays a pivotal role. Next at 11:45 a.m. – 12:45 p.m. in Telegraph Hill attend our session devoted to exploring Product Lifecycle Management’s role in Software Lifecycle Management. This is a thought leadership session with Oracle experts in the field on the importance of change management, and we’ll discuss how Oracle has for years leveraged Agile PLM to develop Agile PLM. If software lifecycle management doesn’t apply to your business or you’d rather engage in some lively one-on-one discussions, we also have a “Supply Chain Meet the Experts” session in Moscone West Room 2001A. Product experts, thought leaders and executives will be on hand to discuss your questions/topics, so come prepared. This session tends to fill up fast so try to get in early. At 1:15 – 2:15 p.m. join us back in Telegraph Hill for a session focused on leveraging the Agile Product Portfolio Management application as the Product Development Master Schedule to improve efficiencies, optimize resources, and gain visibility across projects enterprise-wide to improve portfolio profitability. Customer presenters from Broadcom will explain how they’ve leveraged the product to enable a master schedule with enterprise-level, phase-gate program and project collaboration and resource optimization. Again in Telegraph Hill from 3:30 – 4:30 p.m. we have an interesting session with leading semiconductor customer LSI and partner Kalypso on how LSI leveraged Agile PLM to advance from homegrown applications to complete Product Value Chain Management. That type of transition can be challenging, and LSI details how they were able to achieve their goals and the value they gained along the journey – a fascinating account for any company interested in leveraging best practices to innovate their business processes and even end products. Lastly, we’ll wrap up in Telegraph Hill from 5:00 – 6:00 p.m. with a session on “Ensuring New Product Success by Achieving Excellence in New Product Introduction.” This is a cross-industry session, guaranteed to deliver insight in the often elusive practice of creating winning products, and we’re very excited about. According to IDC Manufacturing Insights analyst Joe Barkai, “Product Failures are not necessarily a result of bad ideas…they are a result of suboptimal decisions.” We’ll show you how to wire your business processes to enhance decision-making and maximize product potential. Now, quickly hit your hotel room to freshen up and then catch one of the many complimentary shuttles to the much-anticipated Oracle Customer Appreciation Event on Treasure Island. We have a very exciting show planned – check out what’s in store here. Thursday, October 4 PLM has a light schedule on Thursday this year with just one session, but this again is one of our best sessions on managing the Product Value Chain: at 11:15 a.m – 12:15 p.m.in Telegraph Hill, it’s a customer and partner driven session with Sonoco Products and Deloitte telling their story about how to achieve integrated change control by interfacing Agile PLM with Oracle E-Business Suite. Sonoco Products, a global manufacturer of consumer and industrial packaging materials, with its systems integrator, Deloitte, is doing this by implementing prebuilt integration (Oracle Design-to-Release Integration Pack for Agile Product Lifecycle Management for Process and Oracle Process) to integrate Agile with Oracle Product Hub/Oracle Product Information Management and Oracle E-Business Suite. This session presents a case study of how Sonoco is leveraging this solution to improve data quality and build a framework for stronger master data governance. Even though that ends our PLM line-up at OpenWorld, there will still be many sessions and activities at the conference, so visit the Oracle OpenWorld website to review agendas and build your schedule. And of course, download and bring this guide and the latest version of the Agile PLM Focus-On Document (available soon!). San Francisco is a wonderful city to explore, and we’re glad you’re considering joining the Agile PLM team at Oracle OpenWorld!  I hope to see you there! Follow me before the conference and on site for real-time updates about #OOW12 on Twitter @Kerrie_Foy or @AgilePLM.

  • Type Casting variables in PHP: Is there a practical example?

    - by Stephen
    PHP, as most of us know, has weak typing. For those who don't, PHP.net says: PHP does not require (or support) explicit type definition in variable declaration; a variable's type is determined by the context in which the variable is used. Love it or hate it, PHP re-casts variables on-the-fly. So, the following code is valid: $var = "10"; $value = 10 + $var; var_dump($value); // int(20) PHP also alows you to explicitly cast a variable, like so: $var = "10"; $value = 10 + $var; $value = (string)$value; var_dump($value); // string(2) "20" That's all cool... but, for the life of me, I cannot conceive of a practical reason for doing this. I don't have a problem with strong typing in languages that support it, like Java. That's fine, and I completely understand it. Also, I'm aware of—and fully understand the usefulness of—type hinting in function parameters. The problem I have with type casting is explained by the above quote. If PHP can swap types at-will, it can do so even after you force cast a type; and it can do so on-the-fly when you need a certain type in an operation. That makes the following valid: $var = "10"; $value = (int)$var; $value = $value . ' TaDa!'; var_dump($value); // string(8) "10 TaDa!" So what's the point? Can anyone show me a practical application or example of type casting—one that would fail if type casting were not involved? I ask this here instead of SO because I figure practicality is too subjective. Edit in response to Chris' comment Take this theoretical example of a world where user-defined type casting makes sense in PHP: You force cast variable $foo as int -- (int)$foo. You attempt to store a string value in the variable $foo. PHP throws an exception!! <--- That would make sense. Suddenly the reason for user defined type casting exists! The fact that PHP will switch things around as needed makes the point of user defined type casting vague. For example, the following two code samples are equivalent: // example 1 $foo = 0; $foo = (string)$foo; $foo = '# of Reasons for the programmer to type cast $foo as a string: ' . $foo; // example 2 $foo = 0; $foo = (int)$foo; $foo = '# of Reasons for the programmer to type cast $foo as a string: ' . $foo; UPDATE Guess who found himself using typecasting in a practical environment? Yours Truly. The requirement was to display money values on a website for a restaurant menu. The design of the site required that trailing zeros be trimmed, so that the display looked something like the following: Menu Item 1 .............. $ 4 Menu Item 2 .............. $ 7.5 Menu Item 3 .............. $ 3 The best way I found to do that wast to cast the variable as a float: $price = '7.50'; // a string from the database layer. echo 'Menu Item 2 .............. $ ' . (float)$price; PHP trims the float's trailing zeros, and then recasts the float as a string for concatenation.

  • Primefaces datatable in-cell edit to update other rows in the same datatable with ajax rowEdit event processing

    - by Java Thu
    I have issue to update other rows in the same datatable when one row updated using primeface datatable in-cell edit ajax rowEdit. But failed to update other row with ajax call. The ajax response only return the same row data which was updated. The codes are as following: <h:form id="testForm"> <p:dataTable id="testDT" var="d" rowIndexVar="rowIndex" value="#{testBean.lists}" editable="true"> <p:column> <f:facet name="header">No</f:facet> <h:outputText value="#{rowIndex}" /> </p:column> <p:column headerText="Value"> <p:cellEditor> <f:facet name="output"> <h:outputText value="#{d.value}" /> </f:facet> <f:facet name="input"> <p:inputText value="#{d.value}" size="5" /> </f:facet> </p:cellEditor> </p:column> <p:column headerText="Edit" style="width:50px"> <p:outputPanel rendered="#{d.editable}"> <p:rowEditor> </p:rowEditor> </p:outputPanel> </p:column> <p:ajax event="rowEdit" update=":testForm:testDT" listener="#{testBean.onRowUpdate}" /> </p:dataTable> </h:form> My TestBean: package web.bean.test; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; import org.primefaces.event.RowEditEvent; @ManagedBean(name="testBean") @ViewScoped public class TestBean { private List<TestData> lists = new ArrayList<>(); @PostConstruct protected void init() { TestData d = new TestData("Row1Data", 1d, true); lists.add(d); d = new TestData("Row1Data", 11.11d, false); lists.add(d); } public void onRowUpdate(RowEditEvent event) { Object o = event.getObject(); if (o != null) { TestData d = (TestData)o; TestData d1 = lists.get(1); d1.setValue(d1.getValue() + d.getValue()); } } public List<TestData> getLists() { return lists; } public void setLists(List<TestData> lists) { this.lists = lists; } } package web.bean.test; public class TestData { private String name; private double value; private boolean editable; public TestData(String name, double value, boolean editable) { super(); this.name = name; this.value = value; this.editable = editable; } public TestData() { } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getValue() { return value; } public void setValue(double value) { this.value = value; } public boolean isEditable() { return editable; } public void setEditable(boolean editable) { this.editable = editable; } } The ajax response body: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><head><link type="text/css" rel="stylesheet" href="/Octopus-G/javax.faces.resource/theme.css.xhtml?ln=primefaces-bluesky" /><link type="text/css" rel="stylesheet" href="/Octopus-G/javax.faces.resource/primefaces.css.xhtml?ln=primefaces&amp;v=3.2" /><script type="text/javascript" src="/Octopus-G/javax.faces.resource/jquery/jquery.js.xhtml?ln=primefaces&amp;v=3.2"></script><script type="text/javascript" src="/Octopus-G/javax.faces.resource/primefaces.js.xhtml?ln=primefaces&amp;v=3.2"></script></head><body> <form id="testForm" name="testForm" method="post" action="/Octopus-G/test.xhtml" enctype="application/x-www-form-urlencoded"> <input type="hidden" name="testForm" value="testForm" /> <div id="testForm:testDT" class="ui-datatable ui-widget"><table role="grid"><thead><tr role="row"><th id="testForm:testDT:j_idt5" class="ui-state-default" role="columnheader"><div class="ui-dt-c"><span>No</span></div></th><th id="testForm:testDT:j_idt8" class="ui-state-default" role="columnheader"><div class="ui-dt-c"><span>Value</span></div></th><th id="testForm:testDT:j_idt12" class="ui-state-default" role="columnheader" style="width:50px"><div class="ui-dt-c"><span>Edit</span></div></th></tr></thead><tfoot></tfoot><tbody id="testForm:testDT_data" class="ui-datatable-data ui-widget-content"><tr data-ri="0" class="ui-widget-content ui-datatable-even" role="row"><td role="gridcell"><div class="ui-dt-c">0</div></td><td role="gridcell" class="ui-editable-column"><div class="ui-dt-c"><span id="testForm:testDT:0:j_idt9" class="ui-cell-editor"><span class="ui-cell-editor-output">1.0</span><span class="ui-cell-editor-input"><input id="testForm:testDT:0:j_idt11" name="testForm:testDT:0:j_idt11" type="text" value="1.0" size="5" class="ui-inputfield ui-inputtext ui-widget ui-state-default ui-corner-all" /><script id="testForm:testDT:0:j_idt11_s" type="text/javascript">PrimeFaces.cw('InputText','widget_testForm_testDT_0_j_idt11',{id:'testForm:testDT:0:j_idt11'});</script></span></span></div></td><td role="gridcell" style="width:50px"><div class="ui-dt-c"><span id="testForm:testDT:0:j_idt13"><span id="testForm:testDT:0:j_idt14" class="ui-row-editor"><span class="ui-icon ui-icon-pencil"></span><span class="ui-icon ui-icon-check" style="display:none"></span><span class="ui-icon ui-icon-close" style="display:none"></span></span></span></div></td></tr><tr data-ri="1" class="ui-widget-content ui-datatable-odd" role="row"><td role="gridcell"><div class="ui-dt-c">1</div></td><td role="gridcell" class="ui-editable-column"><div class="ui-dt-c"><span id="testForm:testDT:1:j_idt9" class="ui-cell-editor"><span class="ui-cell-editor-output">11.11</span><span class="ui-cell-editor-input"><input id="testForm:testDT:1:j_idt11" name="testForm:testDT:1:j_idt11" type="text" value="11.11" size="5" class="ui-inputfield ui-inputtext ui-widget ui-state-default ui-corner-all" /><script id="testForm:testDT:1:j_idt11_s" type="text/javascript">PrimeFaces.cw('InputText','widget_testForm_testDT_1_j_idt11',{id:'testForm:testDT:1:j_idt11'});</script></span></span></div></td><td role="gridcell" style="width:50px"><div class="ui-dt-c"></div></td></tr></tbody></table></div><script id="testForm:testDT_s" type="text/javascript">$(function() {PrimeFaces.cw('DataTable','widget_testForm_testDT',{id:'testForm:testDT',editable:true,behaviors:{rowEdit:function(event) {PrimeFaces.ab({source:'testForm:testDT',process:'testForm:testDT',update:'testForm:testDT',event:'rowEdit'}, arguments[1]);}}});});</script><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="-8223787210091934199:-360328890338571623" autocomplete="off" /> </form></body> </html>
