  • Exporting from SSRS 2008 ReportViewer to Excel Causes Duplicate Columns

    - by Daniel Coffman
    I have a report that groups months by quarters, so each quarter has three months and the display of the months under the quarter is toggled by the quarter header. It looks just fine in the ReportViewer, but when exporting to Excel the first month in the quarter with data is duplicated and appended to the end of the quarter group. Here is what it looks like in the ReportViewer (with Quarters 2 and 4 expanded, note May and June do not have any data and show blank columns by design): http://i.imgur.com/MykZE.png This is how it looks when exported to Excel: http://i.imgur.com/zfLuk.png The collapsed Quarter should only show the LAST month in the quarter. You can see that in the Excel export July is inserted in Q1 even though it should be hidden entirely since that quarter is collapsed, December is appended to Q2, January is inserted into Q3, and April is duplicated and appended to Q4. Exporting the any format OTHER than Excel works correctly and does not insert these columns. A similar bug for rows was filed and marked as "by design": http://connect.microsoft.com/SQLServer/feedback/details/508823/reporting-services-2008-group-by-export-to-excel-duplicate-rows-csv-ok-pdf-ok How do I stop the export to Excel feature from inserting these duplicate columns?

  • libdb4.6-dev vs libdb4.7-dev

    - by routinet
    I want to install PHP 5.3 on Ubuntu Intrepid. To install apxs, I need to install libaprutil1-dev, which depends on libdb4.6-dev. When I look at installing that, apt-get wants to remove the currently installed libdb-dev and libdb4.7-dev. Any advice on how to proceed? [root@server:/usr/local] #> apt-get -s install libaprutil1-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: libaprutil1-dev: Depends: libdb4.6-dev but it is not going to be installed E: Broken packages [root@server:/usr/local] #> apt-get -s install libdb4.6-dev Reading package lists...

  • Cannot rollback ransaction with Entity Framework

    - by Luca
    I have to do queries on uncommitted changes and I tried to use transactions, but I found that it do not work if there are exceptions. I made a simple example to reproduce the problem. I have a database with only one table called "Tabella" and the table has two fields: "ID" is a autogenerated integer, and "Valore" is an integer with a Unique constraint. Then I try to run this code: using (TransactionScope scope = new TransactionScope()) { Db1Container db1 = new Db1Container(); try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); } catch { } try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); //Unique constraint is violated here and an exception is thrown } catch { } try { db1.AddToTabella(new Tabella() { Valore = 2 }); db1.SaveChanges(); } catch { } //scope.Complete(); //NEVER called } //here everything should be rolled back Now if I look into the database it should contain no records because the transaction should rollback, instead I find two records!!!! One with Valore=1 and one with Valore=2. I am missing something? It looks like the second call to SaveChanges method rollback its own changes and "deletes" the transaction, then the third call to SaveChanges commits the changes of the first and the third insert (at this point it is like the transaction not exists). I also tried to use SaveChanges(false) method (even without calling AcceptAllChanges method), but with no success: I have the same behaviour. I do not want the transaction to be rolled back automatically by SaveChanges, because I want to correct the errors (for example by user interaction in the catch statement) and make a retry. Can someone help me with this? It seems like a "bug", and it is giving me a really big headache...

  • Why do I get an error 'Cannot resolve symbol <symbolname>' in ReSharper?

    - by drachenstern
    Using VS2008 and R# 5 I'm running into an odd situation, where on an aspx page I keep getting Cannot resolve symbol 'symbolname' But the code compiles and runs fine. While having a fix for this would be great, I'm just trying to figure out if I'm losing my mind. The CodeFile directive and Inherits directives are fine. If I compile the app or just let devenv sit for a bit it'll go away, but as soon as I save the aspx [via ctrl+s] R# suddenly has trouble with the Inherits attribute and flips out on every method in the page (OnClick etc). // Anonymized of course but otherwise intact <%@ Page AutoEventWireup="true" CodeFile="TestPage.aspx.cs" Inherits="TestPage" Language="C#" MasterPageFile="~/MasterPage.master" Title="Test Page Title" %> This is mostly just a grievance, because since the code compiles it doesn't stop me from doing what I need. I would post a bug report to the JetBrains site but first I would like to know I'm not alone. It could be my machine. Maybe when I roll to VS2010 in a couple weeks this will go away?

  • How to right-justify icon in a JLabel?

    - by geoffreyzheng
    For a JLabel with icon, if you setHorizontalTextPosition(SwingConstants.LEADING), the icon is painted right after text, no matter how wide the label is. This is particularly bad for a list, as the icons would be all over the place depending on how long the text is for each item. I traced the code and it seems to be that in SwingUtilities#layoutCompoundLabelImpl, text width is simply set to SwingUtilities2.stringWidth(c, fm, text), and icon x is set to follow text without considering label width. Here is the simplest case: import java.awt.*; import javax.swing.*; public class TestJLabelIcon { public static void main(String args[]) { EventQueue.invokeLater(new Runnable() { public void run() { JLabel c = new JLabel("abc"); c.setHorizontalTextPosition(SwingConstants.LEADING); c.setHorizontalAlignment(SwingConstants.LEADING); c.setIcon(UIManager.getIcon("FileChooser.detailsViewIcon")); c.setBorder(BorderFactory.createLineBorder(Color.RED)); JFrame frame = new JFrame(); frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); frame.getContentPane().add(c); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); } } You can see that label always fills the frame but icon stays put. You'll get the mirror problem if you set both arguments to TRAILING. I know I can override the UI, or use a JPanel, etc. I just wonder if I'm missing something simple in JLabel. If not, it seems like a Java bug. FYI this is jdk1.6.0_06 on Windows XP.

  • XMLOutputStream, repairing namespaces, and attributes without namespaces

    - by comment_bot
    A simple task: write an element with an unnamespaced attribute: String nsURI = "http://example.com/"; XMLOutputFactory outF = XMLOutputFactory.newFactory(); outF.setProperty(XMLOutputFactory.IS_REPAIRING_NAMESPACES, true); XMLStreamWriter out = outF.createXMLStreamWriter(System.out); out.writeStartElement(XMLConstants.DEFAULT_NS_PREFIX, "element", nsURI); out.writeAttribute(XMLConstants.DEFAULT_NS_PREFIX, XMLConstants.NULL_NS_URI, "attribute", "value"); out.writeEndElement(); out.close(); Woodstox's answer: <element xmlns="http://example.com/" attribute="value"></element> JDK 6 answer: <zdef-159241566:element xmlns="" xmlns:zdef-159241566="http://example.com/" attribute="value"></zdef-159241566:element> What?! Further, if we add a prefix to the element: out.writeStartElement(ns, "element", nsURI); JDK 6 no longer attempts to emit xmlns="": <ns:element xmlns:ns="http://example.com/" attribute="value"></ns:element> I'm fairly sure this is a bug in JDK 6. Am I right? And could anyone suggest a work around that will keep both libraries (and any others) happy? I don't want to require woodstox if I can help it.

It's relatively rare, non-reproducable, and the stacktrace is completely unhelpful because it doesn't include any of my code. Is it a bug in Android itself?

  • code review: Is it subjective or objective(quantifiable) ?

    - by Ram
    I am putting together some guidelines for code reviews. We do not have one formal process yet, and trying to formalize it. And our team is geographically distributed We are using TFS for source control (used it for tasks/bug tracking/project management as well, but migrated that to JIRA) with VS2008 for development. What are the things you look for when doing a code review ? These are the things I came up with Enforce FXCop rules (we are a Microsoft shop) Check for performance (any tools ?) and security (thinking about using OWASP- code crawler) and thread safety Adhere to naming conventions The code should cover edge cases and boundaries conditions Should handle exceptions correctly (do not swallow exceptions) Check if the functionality is duplicated elsewhere method body should be small(20-30 lines) , and methods should do one thing and one thing only (no side effects/ avoid temporal coupling -) Do not pass/return nulls in methods Avoid dead code Document public and protected methods/properties/variables What other things do you generally look for ? I am trying to see if we can quantify the review process (it would produce identical output when reviewed by different persons) Example: Saying "the method body should be no longer than 20-30 lines of code" as opposed to saying "the method body should be small" Or is code review very subjective ( and would differ from one reviewer to another ) ? The objective is to have a marking system (say -1 point for each FXCop rule violation,-2 points for not following naming conventions,2 point for refactoring etc) so that developers would be more careful when they check in their code.This way, we can identify developers who are consistently writing good/bad code.The goal is to have the reviewer spend about 30 minutes max, to do a review (I know this is subjective, considering the fact that the changeset/revision might include multiple files/huge changes to the existing architecture etc , but you get the general idea, the reviewer should not spend days reviewing someone's code) What other objective/quantifiable system do you follow to identify good/bad code written by developers?

  • How to dispose a Writeable Bitmap? (WPF)

    - by Mario
    Some time ago i posted a question related to a WriteableBitmap memory leak, and though I received wonderful tips related to the problem, I still think there is a serious bug / (mistake made by me) / (Confusion) / (some other thing) here. So, here is my problem again: Suppose we have a WPF application with an Image and a button. The image's source is a really big bitmap (3600 * 4800 px), when it's shown at runtime the applicaton consumes ~90 MB. Now suppose i wish to instantiate a WriteableBitmap from the source of the image (the really big Image), when this happens the applications consumes ~220 MB. Now comes the tricky part, when the modifications to the image (through the WriteableBitmap) end, and all the references to the WriteableBitmap (at least those that I'm aware of) are destroyed (at the end of a method or by setting them to null) the memory used by the writeableBitmap should be freed and the application consumption should return to ~90 MB. The problem is that sometimes it returns, sometimes it does not. Here is a sample code: // The Image's source whas set previous to this event private void buttonTest_Click(object sender, RoutedEventArgs e) { if (image.Source != null) { WriteableBitmap bitmap = new WriteableBitmap((BitmapSource)image.Source); bitmap.Lock(); bitmap.Unlock(); //image.Source = null; bitmap = null; } } As you can see the reference is local and the memory should be released at the end of the method (Or when the Garbage collector decides to do so). However, the app could consume ~224 MB until the end of the universe. Any help would be great.

  • Can get coordinates from iPhone simulator, but can't get coordinates from iPhone device

    - by iPhoneARguy
    Hi everyone, I've run into something of a mysterious bug (to me). I have some code to pick out the user's current location on the iPhone SDK. It works fine on the iPhone simulator, but when I try to run it on the actual device, I get a weird error. Here is the code (I am using ASIFormDataRequest to create a POST request): ASIFormDataRequest * request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:@"testauthor" forKey:@"author"]; [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.latitude] stringValue] forKey:@"latitude"]; NSLog(@"%f", datum.location.coordinate.latitude); NSLog(@"%f", datum.location.coordinate.longitude); [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.longitude] stringValue] forKey:@"longitude"]; [request setPostValue:datum.comment forKey:@"comment"]; On the simulator, NSLog does log both the latitude and longitude, but on the iPhone, it does not. Even stranger, when I go through with the debugger on the device, I try "po datum.location", I get <+###, -###> +/- 223.10m (speed 0.00 mps / course -1.00) @ 2010-05-02 22:18:37 -0400 (### replaced by my location) but when I do "(gdb) po datum.location.coordinate" I get: There is no member named coordinate. Do you guys have any idea why this might happen? Thanks in advance for your help!

  • Forms authentication in Silverlight

    - by Matt
    I have a website using forms authentication. Everything runs sweet their. I've got a Silverlight app that uses Duplex messaging to talk to a WCF service. I'd like to be able to authenticate users in my service. I realize that by doing this <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> that my service would then have access to the HttpContext.Current context and I could easily authenticate a user. But herein lies the problem. aspNetCompatibilityEnabled="true" combined with Duplex messaging results in very, very, very slow communication between silverlight and the website (10 seconds or more). Unless I have a configuration wrong, I'm going to assume that this is a bug in WCF / Silverlight. So basically I'm looking for a workaround. One idea I wanted to try was to read the ASPSESSID cookie from the browser and send that value over the wire. But I don't know what to do with the cookie on the service side. Is there some way to authenticate a user by sending their cookie data over duplex messaging?

  • How to prove writing specifications beats code cowboys?

    - by Andrew Grant
    So I have a problem. Or rather my friend has a problem, since I would never write about my company on an internet forum. At my friend's company specification writing is, shall we say, a little underused. There's a deeply ingrained culture of writing code first and asking questions later, whether it's for a library routine or a new tool to inflict on their long suffering designers. This of course leads to situations where functionality is partially correct, incorrect, or just completely missing ("oh, just save before trying anything you may want to undo"). This usually results in a loss of productivity for those poor designers, or beta periods where bug-fixing is largely spent implementing things correctly. My friend's found his suggestions of writing (and testing against) specifications to be generally well received. Most of his colleagues have embraced the wonderful feeling of discovering false-assumptions on paper, instead of at 11pm on a Sunday in the middle of beta. Viva La Revolution! However there are a few who poo-poo anything that stands between their task and a keyboard. They laugh at the thought of actually designing anything, and write code with merry abandon. Mostly these are senior, long employed developers, reluctant to "waste time". The problem is that this second group of heretics invariably produce things (or at least something) quicker than the first. Subsequently this becomes justification along the lines of "It's pointless to write specifications for something as simple as an image resizer! Oh and those bugs where width!=height or the image uses RLE just need a few tweaks". And now the question :) Other than saying "told you so" at the end of a project, what are some good short-term ways to demonstrate how the practice of writing functional or technical specifications leads to better software in the long run? Cheers!

  • Fix common library functions, or abandon then?

    - by Ian Boyd
    Imagine i have a function with a bug in it: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } So the call: MakeLocation("Springfield", "MO"); would return "Springfield, MO" Now there's a slight problem, what if the user called: MakeLocation("Springfield, MO", "OH"); The called it wrong, obviously. But the function would return "Springfield, MO, OH". The system was functioning like this for many years, until i noticed the function being used wrong, and i corrected it. And i also updated the original function to catch such an obvious mistake - in case it's happening elsewhere: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } And testing showed the problem fixed. Except we missed an edge case, and the customer found it. So now the moral dillema. Do you ever add new sanity checks, safety checks, assertions to exising code? Or do you call the old function abandoned, and have a new one: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } Boolean MakeLocation2(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } The same can apply for anything: Question FetchQuestion(Int id) { if (id == 0) throw new EFetchQuestionException("No question ID specified"); ... } Do you risk breaking existing code, at the expense of existing code being wrong?

    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I can't seem to get the wildcard function to work within an eval. The basic code I'm having issues with looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $(join $(SRC_DIR), $(1)/) $(1)_SRC_FILES = $(wildcard $$($(1)_SRC_DIR)*.c) endef $(eval $(call PROGRAM_template, $(PROG_NAME))) all: @echo $(test_SRC_DIR) @echo $(test_SRC_FILES) @echo $(wildcard $(wildcard $(test_SRC_DIR)*.c) When I run make with this, the output is ./src/test [correct list of all .c files in ./src/test/] Basically, the wildcard call within PROGRAM_template is not being eval'd as I expect it. The call results in an empty list. The join call is being eval'd correctly though. So, what am I doing wrong? My guess is that $$($(1)_SRC_DIR) is not correct, but I can't figure out the right way to do it. EDIT Once this was solved, it didn't take long for me to hit another issue with eval. I posted it as a new question at http://stackoverflow.com/questions/2428506/workaround-for-gnu-make-3-80-eval-bug

  • Subsonic 3.0.0.4 Does not Update

    - by geocine
    I tried 3 variants but doesn't seem to update (I am using Linq Templates and MSSQL) Luna.Data.GameDBDB db = new Luna.Data.GameDBDB(); db.Update<Luna.Record.TB_ITEM>() .Set(x => x.ITEM_DURABILITY == Convert.ToInt32(quantity)) .Where(x => x.ITEM_DBIDX == Convert.ToInt32(dbdidx)) .Execute(); Here is the other one var db = new Luna.Data.GameDBDB(); var query = (from p in db.TB_ITEMS where p.ITEM_DBIDX == Convert.ToInt32(dbidx) select p).Single(); query.ITEM_DURABILITY = Convert.ToInt32(quantity); db.tp TP_ITEM_UPDATE(); and the other one var db = new Luna.Data.GameDBDB(); var query = (from p in db.TB_ITEMS where p.ITEM_DBIDX == Convert.ToInt32(dbidx) select p).Single(); query.ITEM_DURABILITY = Convert.ToInt32(quantity); db.Update<Luna.Data.TB_ITEM>(); However it worked using LINQ-to-SQL LunaDataContext db = new LunaDataContext(); var query = (from p in db.TB_ITEMs where p.ITEM_DBIDX == Convert.ToInt32(dbidx) select p).Single(); query.ITEM_DURABILITY = Convert.ToInt32(quantity); db.SubmitChanges(); Is this a bug in 3.0.0.4, the database record couldn't be updated using Linq Templates and ActiveRecord.

  • UINavigationController crash because of pushing and poping UIViewControllers

    - by Wayne Lo
    My question is related to my discovery of a reason for UINavigationController to crash. So I will tell you about the discovery first. Please bare with me. The issue: I have a UINavigationController as as subview of UIWindow, a rootViewController class and a custom MyViewController class. The following steps will get a Exc_Bad_Access, 100% reproducible.: [myNaviationController pushViewController:myViewController_1stInstance animated:YES]; [myNaviationController pushViewController:myViewController_2ndInstance animated:YES]; Hit the left back tapBarItem twice (pop out two of the myViewController instances) to show the rootViewController. After a painful 1/2 day of try and error, I finally figure out the answer but also raise a question. The Solutio: I declared many objects in the .m file as a lazy way of declaring private variables to avoid cluttering the .h file. For instance, #impoart "MyViewController.h" NSMutableString*variable1; @implement ... -(id)init { ... varialbe1=[[NSMutableString alloc] init]; ... } -(void)dealloc { [variable1 release]; } For some reasons, the iphone OS may loose track of these "lazy private" variables memory allocation when myViewController_1stInstance's view is unloaded (but still in the navigation controller's stacks) after loading the view of myViewController_2ndInstance. The first time to tap the back tapBarItem is ok since myViewController_2ndInstance'view is still loaded. But the 2nd tap on the back tapBarItem gave me hell because it tried to dealloc the 2nd instance. Executing [variable release] resulted in Exc_Bad_Access because it pointed randomly (loose pointer). To fix this problem is simple, declare variable1 as a @private in the .h file. Here is my Question: I have been using the "lazy private" variables for quite some time without any issues until they are involved in UINavigationController. Is this a bug in iPhone OS? Or there is a fundamental misunderstanding on my part about Objective C? Please help.

  • Uploadify - Passing Information Back to The Original Form

    - by CccTrash
    I have an Send.aspx page that has an uploadify control on it. Upload.ashx handles the file upload. I am adding a file record to a sql database in the Upload.ashx file and I need to get the ID of that record back from Upload.aspx when it is done. Can't get it working with Sessions. =( Something to do with an Adobe bug? What would the best way to handle this be? Here is the uploadify control: <script type="text/javascript"> // <![CDATA[ var contestID = $('[id$=HiddenFieldContestID]').val(); var maxEntries = $('[id$=HiddenFieldMaxEntries]').val(); var userID = $('[id$=HiddenFieldUserID]').val(); $(document).ready(function() { $('#fileInput').uploadify({ 'uploader': '../uploadify/uploadify.swf', 'script': '../uploadify/Upload.ashx', 'scriptData': { 'contestID': contestID, 'maxEntries': maxEntries, 'userID': userID }, 'cancelImg': '../uploadify/cancel.png', 'auto': true, 'multi': false, 'fileDesc': 'Image Files', 'fileExt': '*.jpg;*.png;*.jpeg', 'queueSizeLimit': 1, 'sizeLimit': 4000000, 'buttonText': 'Choose Image', 'folder': '/uploads', 'onAllComplete': function(event, queueID, fileObj, response, data) { document.getElementById('<%= ButtonCleanup.ClientID %>').click(); } }); }); // ]]></script> Edit: See Answer below...

  • function to get the file name of an URL

    - by user262325
    Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

  • Changes in resolving .resx in Visual Studio 2010?

    - by MADMap
    Hi, I'm working on a quite simple Webpage (MVC2), using localisation based on ResourceFiles. I have the MVC2 Project and the Resources in a seperate Assembly. The Resources contains 3 languages (Resource.resx, Resource.de.resx, Resource.en.resx, Resource.ja.resx) and I'm querying them via the ResourceManager. Call from the .aspx <% Resources.Res resman = new Resources.Res(); %> <%=resman.GetString("String1", new System.Globalization.CultureInfo("en")) %><br /> <%=resman.GetString("String1", new System.Globalization.CultureInfo("ja")) %><br /> <%=resman.GetString("String1", new System.Globalization.CultureInfo("de")) %><br /> ResourceManager: public class Res { private readonly ResourceManager Manager = Resources.Resource1.ResourceManager; public string GetString(string id, CultureInfo info) { return Manager.GetString(id, info); } } And for the compiled Version in VS2008 I get smth like this: String1EN String1JA String1DE Compiled in Visual Studio 2008, this works fine: but I'm having Troubles if I compile the Solution in Visual Studio 2010 (also 3.5 as TargetFramework). There the result shows smth like: String1DEFAULT String1JA String1DEFAULT I don't know what it can be: is this still a bug from the VS2010 RC or am I doing smth. wrong here?

  • Updating textfield in doctrine produces an exception

    - by james-murphy
    I have a textfield that contains say for example the following text:- "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and gravy." This textfield is in a form that simply updates an item record using it's ID. If I edit part of the textfield and replace "and gravy." with "humous." So that the textfield now contains "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and humous." I get the following exception:- Fatal error: Uncaught exception 'Doctrine_Query_Exception' with message 'Unknown component alias humous' in C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php:780 Stack trace: C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(767): Doctrine_Query_Abstract-getQueryComponent('humous') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Set.php(58): Doctrine_Query_Abstract-getAliasDeclaration('humous') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(2092): Doctrine_Query_Set-parse('i.details = 'A ...') C:\Projects\nitrous\lightweight\system\database\Doctrine\Query.php(1058): Doctrine_Query_Abstract-_processDqlQueryPart('set', Array) C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(971): Doctrine_Query-getSqlQuery(Array) C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php(1030): Doctrine_Query_Abstract-_execute(Array) C:\Projects\nitrous\lightweight\system\appl in C:\Projects\nitrous\lightweight\system\database\Doctrine\Query\Abstract.php on line 780 I'm using Doctrine 1.0.6 hooked into CodeIgniter 1.7.0 if anyone is interested. My doctrine query that actually performs the update looks as follows:- public function updateItems($id, $arrayItem) { $query = new Doctrine_Query(); $query->update('Item i'); foreach($arrayItem as $key => $value) { $query->set('i.'.$key, "'".$value."'"); } $query->where('i.id = ?', $id); return $query->execute(); } This seems bizarre because if i replace the entire string "A traditional English dish comprising sausages in Yorkshire pudding batter, usually served with vegetables and humous." with something completely different like just "test" it doesn't throw an exception and works just fine. This baffles me... is it a bug in Doctrine or have I missed something?

  • Problem with Java Applet <--> Javascript communication

    - by davr
    I'm having trouble getting a Java Applet to communicate with the Javascript code on the page the applet is hosted on. It works sometimes, but othertimes it throws an obscure exception, that googling for has not turned up any useful information, besides a few Java bug reports that were never resolved (thanks Sun). Here is the code I am using: JSObject win = JSObject.getWindow(this); Object[] args = new Object[1]; args[0] = "test argument"; String result = (String) win.call("testJSfunc", args); // XXX Here is the exception I get on the line marked // XXX. Note that it is intermittent. Often it works, but sometimes it does not, using the same exact code. Reloading the page repeatedly will produce the error pretty quickly. netscape.javascript.JSException: No registered plugin for applet ID 1 at sun.plugin2.main.client.MessagePassingJSObject.newJSException(Unknown Source) at sun.plugin2.main.client.MessagePassingJSObject.waitForReply(Unknown Source) at sun.plugin2.main.client.MessagePassingJSObject.call(Unknown Source) at TestApplet.testCallJS(TestApplet.java:159) at TestApplet.init(TestApplet.java:139) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Is there another more stable way of communicating between Java and Javascript that I should be using?

  • Linq-to-sql Compiled Query returns object NOT belonging to submitted DataContext ?

    - by Vladimir Kojic
    Compiled query: public static class Machines { public static readonly Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault() ); public static Machine GetMachineById(IUnitOfWork unitOfWork, short id) { Machine machine; // Old code (working) //var machineRepository = unitOfWork.GetRepository<Machine>(); //machine = machineRepository.Find(m => m.MachineID == id).SingleOrDefault(); // New code (making problems) machine = QueryMachineById(unitOfWork.DataContext, id); return machine; } It looks like compiled query is returning result from another data context [TestMethod] public void GetMachinesTest() { using (var unitOfWork = IoC.Get<IUnitOfWork>()) { // Compile Query var machine = Machines.GetMachineById(unitOfWork, 3); } using (var unitOfWork = IoC.Get<IUnitOfWork>()) { var machineRepository = unitOfWork.GetRepository<Machine>(); // Get From Repository var machineFromRepository = machineRepository.Find(m => m.MachineID == 2).SingleOrDefault(); var machine = Machines.GetMachineById(unitOfWork, 2); VerifyHuskyHostMachine(machineFromRepository, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); VerifyHuskyHostMachine(machine, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); Assert.AreSame(machineFromRepository, machine); // FAIL } } If I run other (complex) unit tests I'm getting as expected: An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. Another Important information is that this test is under TransactionScope!
