  • Grails - Recursive computing call "StackOverflowError" and don't update on show

    - by Kedare
    Hello, I have a little problem, I have made a Category domain on Grails, but I want to "cache" the string representation on the database by generating it when the representation field is empty or NULL (to avoid recursive queries at each toString), here is the code : package devkedare class Category { String title; String description; String representation; Date dateCreated; Date lastUpdate; Category parent; static constraints = { title(blank:false, nullable:false, size:2..100); description(blank:true, nullable:false); dateCreated(nullable:true); lastUpdate(nullable:true); autoTimestamp: true; } static hasMany = [childs:Category] @Override String toString() { if((!this.representation) || (this.representation == "")) { this.computeRepresentation(true) } return this.representation; } String computeRepresentation(boolean updateChilds) { if(updateChilds) { for(child in this.childs) { child.representation = child.computeRepresentation(true); } } if(this.parent) { this.representation = "${this.parent.computeRepresentation(false)}/${this.title}"; } else { this.representation = this.title } return this.representation; } void beforeUpdate() { this.computeRepresentation(true); } } There is 2 problems : It don't update the representation when the representation if NULL or empty and toString id called, it only update it on save, how to fix that ? On some category, updating it throw a StackOverflowError, here is an example of my actual category table as CSV : Uploaded the csv file here, pasting csv looks buggy: http://kedare.free.fr/Dist/01.csv Updating the representation works everywhere except on "IT" that throw a StackOverlowError (this is the only category that has many childs). Any idea of how can I fix those 2 problems ? Thank you !

  • Google Maps: openInfoWindowTabsHtml + GDownloadUrl (Ajax call) question

    - by Spiros
    I am facing the following problem. On an Google Map I want to add info windows with tabs, where content is loaded from an external file using the GDownloadUrl method. The code works about fine, but with two problems. a) The first time I click on a marker, nothing hapens. I need to click twice to get an info box. After that it works ok. b) When I close an info box and open it again, the tabs repeat themselves. Every time I reopen the info box, those tabs get repeated. So, if using the code below and open the info box 3 times, I get 6 tabs (Info, Photos, Info, Photos, Info, Photos). Any idea of what I am doing wrong here? I have also tried this with JQuery's $.get method, but the results are exactly the same. function createREMarker(lat,long,reID) { var reMarker = new GMarker(rePoint,iconRE); GEvent.addListener(reMarker, "click", function() { GDownloadUrl('testcontent.php?reID='+reID+'&what=info', function(data) { content1 = data; }); GDownloadUrl('testcontent.php?reID='+reID+'&what=photos', function(data) { content2 = data; }); tabs.push(new GInfoWindowTab('Info', '<div id="mapOverlayContent" style="width:375px; height:220px; overflow:auto;">'+content1+'</div>')); tabs.push(new GInfoWindowTab('Photos', '<div id="mapOverlayContent" style="width:375px; height:220px; overflow:auto;">'+content2+'</div>')); reMarker.openInfoWindowTabsHtml(tabs); }); return reMarker; };

  • Not all parameters get sent in jquery ajax call

    - by rksprst
    I have a strange error where my jquery ajax request doesn't submit all the parameters. $.ajax({ url: "/ajax/doAssignTask", type: 'GET', contentType: "application/json", data: { "just_a_task": just_a_task, "fb_post_date": fb_post_date, "task_fb_postId": task_fb_postId, "sedia_task_guid": sedia_task_guid, "itemGuid": itemGuid, "itemType": itemType, "taskName": taskName, "assignedToUserGuid": assignedToUserGuid, "taskDescription": taskDescription }, success: function(data, status) { //success code }, error: function(xhr, desc, err) { //error code } }); But using firebug (and debugging) I can see that only these variables are posted: assignedToUserGuid itemGuid itemType just_a_task taskDescription taskName It's missing fb_post_date, task_fb_postId, and sedia_task_guid I have no idea what would cause it to post only some items and not others? Anyone know? Data is sent to asp.net controller that returns jsonresult (hence the contentType) Any help is appreciated. Thanks!

  • javascript textbox call event when value changes

    - by Senica Gonzalez
    I have a textbox, and whenever the value of the box changes, I want to check and see if 20 digits have been entered. I thought that I would use the onChange event, but this seems to be interpreted as the onBlur event on IE. So then I thought I would use onKeyDown, but the problem comes in if the user wants to paste a value into the field, then the function never gets called. There are no other form boxes so I can't rely on onBlur or expect that they will change focus ever. How do I do this? I just want to evaluate the value of the textbox everytime the value of the textbox changes. <input type="text" onKeyDown="myfunction()">

  • How to debug .net error where message is masked in Ajax call

    - by Matt Thrower
    Hi, I'm currently working on a page which makes use of the MS Ajax UpdatePanel. However I've run into a strange problem. If I simply compile and view my page, one of the button click events results in an error. However, because the button affects items inside an UpdatePanel the actual exception is hidden from me: all I'm getting is a HTTP 500 error returned to me through the UpdatePanel Javascript. What's odd about this is that if I step through the code line by line in Visual Studio, I don't get the error. The button doesn't cause the behaviour I'm expecting, but it throws no errors. Because the step through isn't causing an error to be thrown, I'm at a loss how I can get to the actual exception message so I can find out where the error is being thrown and debug it. Suggestions gratefully received. Cheers, Matt

  • Usability: call for action

    - by Shyam
    I am designing a page, with tiny portlets. Now, I personally like my actions on the right side, yet I wonder if there are methodologies that are targeted about usability. After all, most applications are aimed at the user. What about yourself? Do you prefer information to be on top, on the left or on the right? I've you need to take some sort of action, do you prefer buttons on the left? References to good books and webpages are very welcome!

  • Parse XML function names and call within whole assembly

    - by Matt Clarkson
    Hello all, I have written an application that unit tests our hardware via a internet browser. I have command classes in the assembly that are a wrapper around individual web browser actions such as ticking a checkbox, selecting from a dropdown box as such: BasicConfigurationCommands EventConfigurationCommands StabilizationCommands and a set of test classes, that use the command classes to perform scripted tests: ConfigurationTests StabilizationTests These are then invoked via the GUI to run prescripted tests by our QA team. However, as the firmware is changed quite quickly between the releases it would be great if a developer could write an XML file that could invoke either the tests or the commands: <?xml version="1.0" encoding="UTF-8" ?> <testsuite> <StabilizationTests> <StressTest repetition="10" /> </StabilizationTests> <BasicConfigurationCommands> <SelectConfig number="2" /> <ChangeConfigProperties name="Weeeeee" timeOut="15000" delay="1000"/> <ApplyConfig /> </BasicConfigurationCommands> </testsuite> I have been looking at the System.Reflection class and have seen examples using GetMethod and then Invoke. This requires me to create the class object at compile time and I would like to do all of this at runtime. I would need to scan the whole assembly for the class name and then scan for the method within the class. This seems a large solution, so any information pointing me (and future readers of this post) towards an answer would be great! Thanks for reading, Matt

  • Navigation to call action for bean class

    - by Muthu
    I am using JSF 2.0 and PrimeFaces 3.0. I have uploaded the images and have to crop the image. The images are uploaded and successfully displayed in the upload pages. When I select the images and click the crop button the corresponding crop bean is not called. If I don't select the image and click the crop button the corresponding crop bean class is called but a NullPointerException occurred. What is the problem?

  • MVC2 Client Validation isn't working when getting form from ajax call

    - by devlife
    I'm trying to use MVC2 client-side validation in a partial view that is rendered via $.get. However, the client validation isn't working. I'm not quite sure what the deal is. [Required(ErrorMessage = "Email is required")] public string Email { get; set; } <% using ( Ajax.BeginForm( new AjaxOptions { Confirm = "You sure?" } ) ) { %> <%: Html.TextBoxFor( m => m.Email, new { @class = "TextBox150" } )%> <%= Html.ValidationMessageFor( m => m.Email )%> <input type="submit" value="Add/Save" style="float: right;" /> <% } %> I'm not doing anything special to render the the partial view. Just putting the html into a div and showing it in a modal popup. On a side note, does anyone know if it's possible to submit the form with client validation without a submit button?

  • Python Process won't call atexit

    - by Brian M. Hunt
    I'm trying to use atexit in a Process, but unfortunately it doesn't seem to work. Here's some example code: import time import atexit import logging import multiprocessing logging.basicConfig(level=logging.DEBUG) class W(multiprocessing.Process): def run(self): logging.debug("%s Started" % self.name) @atexit.register def log_terminate(): # ever called? logging.debug("%s Terminated!" % self.name) while True: time.sleep(10) @atexit.register def log_exit(): logging.debug("Main process terminated") logging.debug("Main process started") a = W() b = W() a.start() b.start() time.sleep(1) a.terminate() b.terminate() The output of this code is: DEBUG:root:Main process started DEBUG:root:W-1 Started DEBUG:root:W-2 Started DEBUG:root:Main process terminated I would expect that the W.run.log_terminate() would be called when a.terminate() and b.terminate() are called, and the output to be something likeso (emphasis added)!: DEBUG:root:Main process started DEBUG:root:W-1 Started DEBUG:root:W-2 Started DEBUG:root:W-1 Terminated! DEBUG:root:W-2 Terminated! DEBUG:root:Main process terminated Why isn't this working, and is there a better way to log a message (from the Process context) when a Process is terminated? Thank you for your input - it's much appreciated.

  • Client Web Service call over SSL using Apache Axis

    - by java_pill
    I'm using Apache Axis 1.5.1 to code a web service client connecting to a service over SSL. My application is running in Tomcat with SSL configuration setup in JKS. However, when I connect to the server, the connection is failing because the cert from our client is not being sent to the server. Is this something that has to be set in the client through code? Also note that the server does not need any user name or password authentication. With SSL turned off, everything works fine. Thanks,

  • Call to C++ COM interface from C# being blocked

    - by dauphic
    I have a C++ DLL that exposes a COM interface. A C# application uses the COM interface. I've recently run into a problem where some calls to the COM interface are taking 500-5000 ms to return, though they should return almost instantly (no longer than 10 ms). Profiling the application shows that all of the delay is being caused by the 'thread being blocked;' no other information is available. There are no locks, etc. in my code, so the blocking has to be occurring internally in the COM/interop code. Only one thread interfaces with the COM DLL. Any ideas what could be causing this, and how I would fix it? EDIT: Further investigation shows that the block is occuring when the C++ returns to the C#.

  • Service Call very slow if going through HttpHandler

    - by JohnIdol
    I have a WCF client pointing to a WebSphere service. All is good in normal situation except when my calls to the service originate from an HttpHandler - in this case the calls are extremely slow (it takes up to 10 times longer). If I send the exact same envelopes through Soap-UI or without an HttpHandler it's all good. If the envelope is the same the only thing left is the HttpHeader. Would the fact that I am going through an HttpHandler cause changes HttpHeaders compared to normal scenarios? What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

  • call method in a subclass of UIView

    - by rdesign
    Hey, I've got a UIViewController and an own class, a subclass of UIView. In my ViewController I make a instance of the uiview. If I tap the uiview a function gets called within it and an overlay appears. TO get rid of that overlay later the user has to tap somewhere on the screen(besides the instance of my class) How do I tell my class to dismiss the overlay? I already thought of delegate. So my thoughts were to make a MyUIViewControllerdelegate. If my viewcontroller receives a tap the delegate should be called. THe only problem is how do I tell my subclass that it should receive that delegate? I Have no instance of my viewcontroller in my subclass so I can not set the delegate. Any Ideas? Hope my problem is clear :) Thanks a lot

I have tried but only get undefined values. In this situation, it will be acceptable to use synchronous calls. Any advice appreciated. Thanks

  • Call to undefined function 'Encrypt' - Attempting to Link OMF Lib

    - by Changeling
    I created a DLL using Visual Studio 2005 VC++ and marked a function for export (for testing). I then took the .LIB file created, and ran it through the COFF2OMF converter program bundled with Borland C++ Builder 5 and it returns the following: C:\>coff2omf -v -lib:ms MACEncryption.lib MACEncryption2.lib COFF to OMF Converter Version 1.0.0.74 Copyright (c) 1999, 2000 Inprise Corporat ion Internal name Imported name ------------- ------------- ??0CMACEncryptionApp@@QAE@XZ ?Decrypt@CMACEncryptionApp@@QAEXXZ Encrypt Encrypt@0 I added the MACEncryption2.lib file to my C++ Builder 5 Project by going to Project-Add to Project.. and selecting the library. The application links, but it cannot find the Encrypt function that I am declaring for export as follows in the VC++ code: extern "C" __declspec(dllexport) BSTR* __stdcall Encrypt() { CoInitialize(NULL); EncryptionManager::_EncryptionManagerPtr pDotNetCOMPtr; HRESULT hRes = pDotNetCOMPtr.CreateInstance(EncryptionManager::CLSID_EncryptionManager); if (hRes == S_OK) { BSTR* str = new BSTR; BSTR filePath = (BSTR)"C:\\ICVER001.REQ"; BSTR encrypt = (BSTR)"\"test"; pDotNetCOMPtr->EncryptThirdPartyMessage(filePath, encrypt, str); return str; } return NULL; CoUninitialize (); } C++ Builder Code: __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { Encrypt(); } (Yes I know I am encapsulating another DLL.. I am doing this for a reason since Borland can't 'see' the .NET DLL definitions) Can anyone tell me what I am doing wrong so I can figure out why Builder cannot find the function Encrypt() ?

  • Saving multiple objects in a single call in rails

    - by CaptnCraig
    I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?
