  • Supplying a callback to Jeditable

    - by pjmorse
    Summary: When I try supplying a onsubmit or onreset callback to Jeditable, I get Object [function] has no method 'apply' errors. How I got here: I've been working on a rails plugin to supply Jeditable and jWYSIWYG for in-place WYSIWYG editing. Development is driven by a Rails project I'm working on which asks for specific functions. One of the options I added was the ability to trigger Jeditable's edit mode using a button instead of clicking on the editable text itself, following the pattern suggested in this answer. The next step, though, is to hide the button while in edit mode, and reveal it again when leaving edit mode. The hide is easy enough; I just added a line to the triggering function which sends .toggle() to the button. Reveal is trickier. I figure I need to .toggle() again on submit or cancel, and helpfully, Jeditable offers onsubmit and onreset callbacks. However, when I try using those callbacks, I get this Object [something] has no method 'apply' errors. What I'm trying: Because this is in the context of a Rails helper, the actual mechanics are a little more involved than this, but the upshot is that I'm trying to follow this pattern, handing Jeditable this in the args: "onsubmit":"showTrigger", and then including this script: function showTrigger(settings, original) { $(".edit_trigger[id='element_id']").toggle(); } However, on submitting changes or canceling an edit, I get the error Object showTrigger has no method 'apply' ...as described above. I also tried sending in a function directly as the "onsubmit" argument (i.e. "onsubmit": "function(settings, original){$(\".edit_trigger[id='element_id']\").toggle();}" and then I just get Object function(settings, original){$(\".edit_trigger[id='element_id']\").toggle();} has no method 'apply' instead. There must be something wrong with how I'm handing in this callback. Any ideas? ETA: This answer suggests to me that somehow I'm providing a string to Jeditable when it expects a function instead. However, because I'm working within the context of a Rails helper, I'm not at all sure how to fix that - the "showTrigger" bit is set as a Ruby variable in the helper, and although window.showTrigger() is defined when the window is loaded, I don't know how to designate that function within a Ruby variable such that it will be recognized as a function at page load time.

  • .NET Weird character encoding issue

    - by born to hula
    Our globalization mechanism stores error messages in a SQL 2005 DB. Some of the error messages are used as subjects on email messages sent to the development team. Recently, with no clear reason, we started receiving emails with strangely encoded subjects, such as: =?utf-8?B?Qm1mQm92ZXNwYS5Qb3NUcmFkaW5nRXNwZWNpZmljYWNhbyAtIFN1Y2Vzc28gbm8gcmVwcm 9jZXNzYW1lbnRvLiBEYXRhIFByZWfDo28gPSAzMS8wMy8yMDEwIDAwOjAwOjAwIC0gTsO6bWVyby BkbyBFdmVudG8gZGUgTmVnw7NjaW8gPSAxMDAyIC0gQ8OzZGlnbyBOYXR1cmV6YSBkYSBPcGVyY cOnw6NvID0gQyAtIFNlcn... We don't have any clue on the reason this is happening, nor which encoding pattern is being used here (maybe utf-8?). I'd really appreciate some help.

  • What's the fastest way to determine if a file adheres to a particular class's NSCoding implementatio

    - by Justin Searls
    Given: An application that accesses a directory of files: some plain text, some binary files that adhere to a particular NSCoding implementation, and perhaps other binary files it simply doesn't understand how to process. I want to be able to figure out which of the files in that directory adhere to my NSCoding class, and I'd prefer not to have to fall back on the naïve approach of loading the entirety of each file into memory, attempting to unarchive each. Anyone have an elegant approach or pattern to this problem?

  • Autofac in web applications, where should I store the container for easy access

    - by michielvoo
    I'm still pretty new to using Autofac and one thing I miss in the documentation and examples is how to make it easy to get to the configured container from different places in a web application. I know I can use the Autofac controller factory to automatically resolve constructor injected dependencies for controllers, but how about the other stuff you might need to resolve that is not injected yet. Is there an obvious pattern I am not aware of for this? Thank you!

  • Cross field validation in jsf h:datatable using p:calendar

    - by Matt Broekhuis
    I noticed this question was asked, but it has not been answered correctly. I have a datatable that has two columns start date and end date. Both contain primefaces p:calendar controls in them. I need to ensure that for each row that the date in column1 is not after the date in column2. I would like to tie this into the JSF validation framework, but I'm having trouble. i've tried marking the datatable rowStatePreserved="true" , this allows me to get the values, but something is still wrong as when it fails, all the values in the first row overwrite all the other values. What am I doing wrong, or should I be using a completely different strategy? xhtml code <h:form> <f:event type="postValidate" listener="#{bean.doCrossFieldValidation}"/> <p:dataTable id="eventDaysTable" value="#{course.courseSchedules}" var="_eventDay" styleClass="compactDataTable" > <p:column id="eventDayStartColumn"> <f:facet name="header"> Start </f:facet> <p:calendar id="startDate" required="true" value="#{_eventDay.startTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> <p:column id="eventDayEndColumn"> <f:facet name="header"> End </f:facet> <p:calendar id="endDate" required="true" value="#{_eventDay.endTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> </p:dataTable> </h:form> validationCode public void doCrossFieldValidation(ComponentSystemEvent cse) { UIData eventsDaysStable = (UIData) cse.getComponent().findComponent("eventDaysTable"); if (null != eventsDaysStable && eventsDaysStable.isRendered()) { Iterator<UIComponent> startDateCalendarIterator = eventsDaysStable.findComponent("eventDayStartColumn").getChildren().iterator(); Iterator<UIComponent> endDateCalendarIterator = eventsDaysStable.findComponent("eventDayEndColumn").getChildren().iterator(); while (startDateCalendarIterator.hasNext() && endDateCalendarIterator.hasNext()) { org.primefaces.component.calendar.Calendar startDateComponent = (org.primefaces.component.calendar.Calendar) startDateCalendarIterator.next(); org.primefaces.component.calendar.Calendar endDateComponent = (org.primefaces.component.calendar.Calendar) endDateCalendarIterator.next(); Date startDate = (Date) startDateComponent.getValue(); Date endDate = (Date) endDateComponent.getValue(); if (null != startDate && null != endDate && startDate.after(endDate)) { eventScheduleChronologyOk = false; startDateComponent.setValid(false); endDateComponent.setValid(false); } } if (!eventScheduleChronologyOk) { showErrorMessage(ProductManagementMessage.PRODUCT_SCHEDULE_OUT_OF_ORDER); } } }

  • How to use Linq with Castle ActiveRecord

    - by Ronnie Overby
    I am playing around with Castle ActiveRecord and noticed that the download included the file, Castle.ActiveRecord.Linq.dll. I haven't found any documentation for using Linq with ActiveRecord, only some old blog posts. What is the usage pattern? Is Castle.ActiveRecord.Linq ready for production use? I'm using reflector, pending an answer.

  • C++ Program Always Crashes While doing a std::string assign

    - by bbazso
    I have been trying to debug a crash in my application that crashes (i.e. asserts a * glibc detected free(): invalid pointer: 0x000000000070f0c0 **) while I'm trying to do a simple assign to a string. Note that I'm compiling on a linux system with gcc 4.2.4 with an optimization level set to -O2. With -O0 the application no longer crashes. E.g. std::string abc; abc = "testString"; but if I changed the code as follows it no longer crashes std::string abc("testString"); So again I scratched my head! But the interesting pattern was that the crash moved later on in the application, AGAIN at another string. I found it weird that the application was continuously crashing on a string assign. A typical crash backtrace would look as follows: #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #1 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #2 0x00000000004d8cb7 in people_streamingserver_sighandler (signum=6) at src/peoplestreamingserver.cpp:487 #3 <signal handler called> #4 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #5 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #6 0x00007f2c26680ce0 in ?? () from /lib64/libc.so.6 #7 0x00007f2c270ca7a0 in std::string::assign (this=0x7f2c21bc8d20, __str=<value optimized out>) at /home/bbazso/ThirdParty/sources/gcc-4.2.4/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/basic_string.h:238 #8 0x00007f2c21bd874a in PEOPLESProtocol::GetStreamName (this=<value optimized out>, pRawPath=0x2342fd8 "rtmp://127.0.0.1/mp4:pop.mp4", lStreamName=@0x7f2c21bc8d20) at /opt/trx-HEAD/gcc/4.2.4/lib/gcc/x86_64-pc-linux-gnu/4.2.4/../../../../include/c++/4.2.4/bits/basic_string.h:491 #9 0x00007f2c21bd9daa in PEOPLESProtocol::SignalProtocolCreated (pProtocol=0x233a4e0, customParameters=@0x7f2c21bc8de0) at peoplestreamer/src/peoplesprotocol.cpp:240 This was really weird behavior and so I started to poke around further in my application to see if there was some sort of memory corruption (either heap or stack) error that could be occurring that could be causing this weird behavior. I even checked for ptr corruptions and came up empty handed. In addition to visual inspection of the code I also tried the following tools: Valgrind using both memcheck and exp-ptrcheck electric fence libsafe I compiled with -fstack-protector-all in gcc I tried MALLOC_CHECK_ set to 2 I ran my code through lint checks as well as cppcheck (to check for mistakes) And I stepped through the code using gdb So I tried a lot of stuff and still came up empty handed. So I was wondering if it could be something like a linker issue or a library issue of some sort that could be causing this problem. Are there any know issues with the std::string that make is susceptible to crashing in -O2 or maybe it has nothing to do with the optimization level? But the only pattern that I can see thus far in my problem is that it always seems to crash on a string and so I was wondering if anyone knew of any issues that my be causing this type of behavior. Thanks a lot!

  • Can regular expressions be used to match nested patterns?

    - by Richard Dorman
    Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times. For example, can a regular expression match an opening and closing brace when there are an unknown number of open closing braces nested within the outer braces. For example: public MyMethod() { if (test) { // More { } } // More { } } // End Should match: { if (test) { // More { } } // More { } }

  • Write Scheme data structures so they can be eval-d back in, or alternative

    - by Jesse Millikan
    I'm writing an application (A juggling pattern animator) in PLT Scheme that accepts Scheme expressions as values for some fields. I'm attempting to write a small text editor that will let me "explode" expressions into expressions that can still be eval'd but contain the data as literals for manual tweaking. For example, (4hss->sexp "747") is a function call that generates a legitimate pattern. If I eval and print that, it becomes (((7 3) - - -) (- - (4 2) -) (- (7 2) - -) (- - - (7 1)) ((4 0) - - -) (- - (7 0) -) (- (7 2) - -) (- - - (4 3)) ((7 3) - - -) (- - (7 0) -) (- (4 1) - -) (- - - (7 1))) which can be "read" as a string, but will not "eval" the same as the function. For this statement, of course, what I need would be as simple as (quote (((7 3... but other examples are non-trivial. This one, for example, contains structs which print as vectors: pair-of-jugglers ; --> (#(struct:hand #(struct:position -0.35 2.0 1.0) #(struct:position -0.6 2.05 1.1) 1.832595714594046) #(struct:hand #(struct:position 0.35 2.0 1.0) #(struct:position 0.6 2.0500000000000003 1.1) 1.308996938995747) #(struct:hand #(struct:position 0.35 -2.0 1.0) #(struct:position 0.6 -2.05 1.1) -1.3089969389957472) #(struct:hand #(struct:position -0.35 -2.0 1.0) #(struct:position -0.6 -2.05 1.1) -1.8325957145940461)) I've thought of at least three possible solutions, none of which I like very much. Solution A is to write a recursive eval-able output function myself for a reasonably large subset of the values that I might be using. There (probably...) won't be any circular references by the nature of the data structures used, so that wouldn't be such a long job. The output would end up looking like `(((3 0) (... ; ex 1 `(,(make-hand (make-position ... ; ex 2 Or even worse if I could't figure out how to do it properly with quasiquoting. Solution B would be to write out everything as (read (open-input-string "(big-long-s-expression)")) which, technically, solves the problem I'm bringing up but is... ugly. Solution C might be a different approach of giving up eval and using only read for parsing input, or an uglier approach where the s-expression is used as directly data if eval fails, but those both seem unpleasant compared to using scheme values directly. Undiscovered Solution D would be a PLT Scheme option, function or library I haven't located that would match Solution A. Help me out before I start having bad recursion dreams again.

  • Java constructor with large arguments or Java bean getter/setter approach

    - by deelo55
    Hi, I can't decide which approach is better for creating objects with a large number of fields (10+) (all mandatory) the constructor approach of the getter/setter. Constructor at least you enforce that all the fields are set. Java Beans easier to see which variables are being set instead of a huge list. The builder pattern DOES NOT seem suitable here as all the fields are mandatory and the builder requires you put all mandatory parameters in the builder constructor. Thanks, D

  • Accessing different connection strings at runtime in ASP.NET MVC 1

    - by Neil T.
    I'm trying to implement integration testing in my ASP.NET MVC 1.0 solution. The technologies in use are LINQ-to-SQL, NUnit and WatiN. I recently discovered a pattern that will allow me to create a testing version of the database on the fly without modifying the development version of the database. I needed this behavior in order to run my user interface tests in WatiN that may modify the database. The plan is to modify the connection string in the Web.config file, and pass that new connection string to the DataContext constructor. This way, I don't have to add routes or modify my URLs in order to perform the integration testing. I've set up the project so that the test setup can modify the connection string to point to the test database when the tests are running. The connection string is stored in web.config. The problem I'm having is that when I try to run the tests, I get a NullReferenceException when trying to access the HTTPContext. From everything that I have read so far, the HTTPContext is only available within the context of a controller. Here is the code for the property that is supposed to give me the reference to the Web.config file: private System.Configuration.Configuration WebConfig { get { ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap(); // NullReferenceException occurs on this line. fileMap.ExeConfigFilename = HttpContext.Current.Server.MapPath("~\\web.config"); System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None); return config; } } Is there something that I am missing in order to make this work? Is there a better way to accomplish what I'm trying to achieve? UPDATE: I decided to abandon the modification of Web.config in lieu of a "request-scoped DataContext" pattern that I found here. From the looks of it, I believe it should give me the results I'm looking for. However, during the TextFixtureSetUp, I try to create a new copy of the database for testing purposes, and it fails silently. When I get to the tests, the repository still uses the production database connection string to load data.
