GWT2.8.1 errors "Exception: com.google.gwt.core.client.JavaScriptException: (TypeError) : object_0_g$.getXXX_30_g$ is not a function"
Hi all
since upgrading to GWT2.8.1 I am seeing an error message never before
encountered (and I've been developing with GWT for numerous years).
"Exception: com.google.gwt.core.client.JavaScriptException: (TypeError)
: object_0_g$.getXXX_30_g$ is not a function"
Reverting back to GWT2.8 caused the problem to disappear.
The problem has only occurred in anonymous classes up until now (but no
idea if that is important or not).
For example, I have
public class SomeTable extends DataGrid {
private void initTable() {
TextColumn arcIdCol = new TextColumn() {
@Override
public String getValue(SomeClass object) {
logger.info("= " + object.get()); // EXECUTION PROBLEM HERE
return object.get()
}
};
..
}
The java code compiles fine, and the GWT compilation works fine when
SuperDev mode is launched (all done in Eclipse).
When the logger.info line is reached, the error ".. not a function" is
thrown.
Examining in the browser debugger, I can see that the prototype (_proto_)
associated to the " SomeClass object" parameter does not contain the
function get.
If I re-edit the file SomeClass.java, adding in a new dummy method, and
re-save, then this time it works -- the function get exists.
Sounds like an incomplete incremental compilation?
What is frustrating is that the problem is sporadic - other classes
employing the same design patterns work fine.
Has anyone encountered similar issues?

Hi Ian, Yes, we are still seeing the problem. I've put it aside for the moment, hoping to revisit once we upgrade to a new GWT Release Candidate.

GWT2.8 : org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration
Hi, I am developing a that contains within it - a vanilla HttpServlet - a GWT RPC Service implementation (RemoteServiceServlet) I am currently using [GWT2.8rc1]. Both servlets manipulate XML documents, and hence make calls to the following code DocumentBuilderFactory docfactory = DocumentBuilderFactory.newInstance(); docfactory.setNamespaceAware(true); DocumentBuilder builder = docfactory.newDocumentBuilder(); // * problem here * When I launch the application in Eclipse, using the embedded Jetty container, the vanilla HttpServlet will fail at the line DocumentBuilder builder = docfactory.newDocumentBuilder(); // * problem here * The error message is java.lang.ClassCastException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration Having done some research, this exception is typically raised when there are several Xerces implementations found on the classpath. (I can only see Xerces implementations in gwt-dev and in Eclipse as a plugin). For the GWT RPC Service implementation, launched as part of the same , the XML document processing works fine - i.e. no exception raised. If I comment out in the web.xml file the GWT-RPC servlet defintion, then the vanilla HttpServlet will perform the XML document processing without an exception.

Re: Request Context clear queue on method invocations when onConstraintViolation is called
What about if your request context interface has multiple methods? I have a save and a cancel on mine, and I have to use the cancel to do some server side cleanup if the user decides to abandon their changes. If I call save and it fails validation or whatever, and then the user decides to cancel, then the save method invocation is still present on the request context, when for a cancel call I only want a cancel call in the queue. I really don't understand why there is no API for manipulating the invocation queue, as it seems a valid thing to want to do. I can probably make a separate context for the cancel, and do it this way, as in that case I'm not interested in anything that has changed in the 'editing' context. Is this the right approach? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Request Context clear queue on method invocations when onConstraintViolation is called
In fact I can't just make a new context and send cancel(Proxy).fire() to it as the proxy was created by the original request (the one holding the save call in its invocation queue) , and it tries to call edit on the proxy in the GWT internals when I call cancel on the new request (why, I don't know - I only want to pass it across as an argument, and have no intention of editing it in the new context) and then falls over because the proxy was already edited in the original request. I guess my cancel will have to take different arguments and do the query for the object I want to get hold of and clean up in my server code (annoying as I'll be duplicating what the find methods on the locator do - albeit my factoring will mean I can do it without duplicating code, but still.).

Re: ui:style src attribute causes error in the Google Eclipse plugin
Philippe, I have found a way to use the src/main/gwt folder work seamless between m2e, GPE and maven-gwt-plugin. When using this method src/main/gwt shows up in Eclipse as a src folder and nothing is excluded. Also doing a gwt:compile and gwt:run from the command line worked fine as well. You can safely put your .gwt.xml files in this folder and even GPE will be able find them.

click event completes in hosted mode but not once deployed?
Hi Everyone In my web application i have some links that, when clicked are supposed to: - use an RPC to get some data from the server - construct a new Panel - insert the panel into the browser document My solution seems to work as expected while in hosted mode, but not once the application is deployed. I am using App Engine as a server. From what I can tell, the clickEvent does cause the asynchronous RPC to fire, and the correct results are returned to the client. I see the values I expect in FireBug's header view. For some reason the clickEvent is not finishing as i would expect - the new panel is not displayed. There appear to be no errors on the server, as the logs remain clean. Any help on how to debug this would be much appreciated. One possible problem area may be my use of java packages on the client? I have my code in several packages: com.app.client com.app.client.model com.app.client.util etc I have not made any changes to my gwt.xml file, as I'm somewhat confused about modules. With no changes here, the app is working as expected in hosted mode, and the app does compile without error.

Re: click event completes in hosted mode but not once deployed?
ok, I found my problem. In my client code, I had a try/catch expression that would ignore a NullPointerException when a Map entry was attepted that didn't exist. I replaced this, and my web app works as expected. On a similar note, does anybody have any javascript debugging tips for GWT? I have no way to set breakpoints / or otherwise observe the javascript of my app. this is making debugging with alert statements tedious.

Calling remote service defined in different module
I have a remote service MyServlet defined in a module module1, and I wish to call the service from a different module module2. The trouble is that the URL that is generated, and used for the POST is of the form module2/MyServlet instead of module1/MyServlet. This doesn't match the URL mapping in my web.xml What should I do here? Should I add a URL servlet mapping for each module that uses the servlet?

[gwt-contrib] Re: GWT Flash components and toggling visibility issue
Ray, Thanks for the help. What you described is kinda the workaround that I was just coding up while I was waiting for my posting to appear. I hadn't planned on keeping all of my state in the GWT, but to get this to work I guess I'll have to go that route. The solution that I'd love to see here would be for the browsers to standardize and adopt one of the Canvas 3D approaches and I can drop the Flash... but I'm not going to hold my breath... Thanks, Darren On Mar 10, 4:01 pm, Ray Cromwell cromwell...@gmail.com wrote: You can try looking at my FlashCanvas class (http://code.google.com/p/gwt-chronoscope/source/browse/trunk/chronosc...) Essentially what I do is that on startup of the SWF, I invoke a GWT callback method. This method setups up some state, and then calls the SWF and tells it that it's ready as well. What happens if you toggle display: none? The next time the SWF is loaded, it calls the callback again, but this time, the GWT code sees that it is not the first time, so is redraws everything from scratch. This approach is only viable if you are keeping most of your state in GWT code. If you're using Flash as just a 3D renderer, consider it just like a DirectX/Direct3D surface, which can be lost if the user ALT-TABs your game or application. You detect the loss of rendering surface, and reupload all the state back. I don't really think there's a good solution for this. Sure, you could change tab panel to use 'visibility: hidden', but there's many other GWT panels that can't use visibility: hidden, because they need to resize when components are hidden (e.g. DisclosurePanel, StackPanel, etc) Then you'd be forcing some kind of hack into all GWT components to use 'visibility: hidden, width: 0, height: 0, border: 0, padding: 0, margin: 0' just to hide the Flash component. One thing you'll also find that that Flash's ExternalInterface doesn't like to be deeply nested in HTML on Internet Explorer, so if you place your object/embed inside of a form tag, it will break (see the fixSWFinIE() function in FlashCanvas). Secondly, putting the object inside of a p also breaks ExternalInterface for me on IE6. -Ray On Tue, Mar 10, 2009 at 10:55 AM, Darren siegel.dar...@gmail.com wrote: I have a GWT application that utilizes a Flash/PaperVision3D component that I have created. The GWT app places creates instances of the Flash component on different tabs in a tab panel. During execution of the app, everything works great until the user starts clicking in between tabs. At the GWT level, the generated JavaScript is changing the style.display attribute to hide and show the contents of the tabs. It appears that the Flash component (included in the page by natively scripting an 'embed' tag) is reloading/restarting each time that it is made visible. How can I prevent it from restarting/reloading? I don't have much control at all over the fact that the DIV tag is getting set to style.display = 'none', as that is being controlled by the autogenerated GWT code, so I can't take the route of playing some games of setting transparency or shrinking it down. Is there some setting perhaps in the Flex/Flash development to allow it to do this? Or maybe in the Embed tag? Or even at the JavaScript level? It seems that a side effect of the unloading/reloading is that the API that I export from my Flash component via ExternalInterface is not available when the component is not visible. I know there are plenty of GWT Flash based components out there? How have you folks solved this problem in those and similar components?
