Issues - Co-existence of GXT3 with GXT2.2.5 - Deferred binding failed Error

[dxdev]

Hi,
I tried to upgrade my application to use GXT3 with existing GXT2 hence I followed the steps mentioned in GXT3 setup.txt and steps in URL - http://www.sencha.com/learn/running-...cWGog80wlWGeiU

But, when I run my project in DevMode I got following errors:

13:01:03.160 [ERROR] [myproj] Deferred binding failed for 'com.google.gwt.user.client.UserAgentAsserter.UserAgentProperty'; expect subsequent failures

 13:01:03.209 [ERROR] [dxweb] Unable to load module entry point class com.google.gwt.user.client.UserAgentAsserter (see associated exception for details)

FYI:
I changed the project module file(xxx.gwt.xml) and made necessary changes in project build path. Added the required JARs in lib folder of the module which creates EAR file.
My 'xxx.gwt.xml' has following :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.1.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.1.0/distro-source/core/src/gwt-module.dtd">

[sven]

This is hard to say. Is that the full stacktrace or are there more excetions, as the stacktrace indicates this?
Also what is the version of GWT you are using? Is it really 2.1.0 as your xml file indicates?

[dxdev]

Thanks Sven for instant response. I am using GWT 2.4.0, as you pointed I changed the xml file entry to -

<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.4.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.4.0/distro-source/core/src/gwt-module.dtd">

But, still I am getting the same error.
The DevMode error stacktrace is:

[sven]

Hard to say without being able to reproduce this on my own.

Have you tried to switch the inherit order, like first loading GXT 3 and than GXT 2?

[dxdev]

I referred to URL (http://www.sencha.com/forum/showthre...dgeImpl.create) - any solution provided to fix the reported issue?

[dxdev]

Sven,
I found one workaround.
As the issue is related with GWT UserAgentPropertyGenerator.java, hence I used 'com.sencha.gxt.core.rebind.useragent.UserAgentPropertyGenerator' instead.
Although the application is loading but now I am getting Serialization Policy related exception.

Workaround:
I added following entry in my module xml file:

<!-- Workaround - Remove when GWT UserAgentPropertyGenerator gets fixed - Using Sencha UserAgentPropertyGenerator without test on GoogleFrame -->
    <property-provider name="user.agent" generator="com.sencha.gxt.core.rebind.useragent.UserAgentPropertyGenerator"/>

    <!-- Mask error message -->
    <set-configuration-property name="user.agent.runtimeWarning" value="false"/>
        
    <!-- IE -->    
    <set-property name="user.agent" value="ie6" />
    <extend-property name="user.agent" values="ie8" />
    <extend-property name="user.agent" values="ie9" />
    <!-- FF -->
    <extend-property name="user.agent" values="gecko1_8" />
    <!-- CHROME -->
    <extend-property name="user.agent" values="safari" />                
    <!-- Workaround - End -->

As you can see, this is hardcoding 'user.agent', hence expecting some update on GXT to resolve this hardcoding.

SerializationPolicy Exception Issue:
My application's models implement BeanModelTag, IsSerializable, Serializable interfaces.

As updated, after the module the application is loading fine. But in DevMode - now I am getting exception related to Serialization policy:

2012-06-20 20:28:01,588 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/myProj]] (http-localhost%2F127.0.0.1-8080-4) myPackageService: ERROR: The serialization policy file '/myproj/F1A0525D5045A9D4B8A55884842E03D1.gwt.rpc' was not found; did you forget to include it in this deployment?

With GXT2.2.5 same models implementing BeanModelTag and Serializable worked fine.
Need your suggestion.

[sven]

That workaround is not a good one, as it will introduce more issues than it solves.

The best i think is to open a real support ticket in your ticket system and schedule a remote desktop session, so we can debug the problem directly in yout setup. Would this be possible?

[TrojanMyth]

I have a problem too about this problem. How could you solve this .

[TrojanMyth]

I solved problem.

1- I updated GWT version 2.4 to 2.5 RC2
2- I cleaned Browser Cache/Coockie/etc
3- I rebuilded application problem is solved.

[Colin Alworth]

Whenever I've seen this error in the past, it has been from multiple, inconsistent copies of GWT on the classpath. Moving to 2.5.0 RC2 in all places seems to have cleared out any other possible copies, but if the issue comes back, be sure to check that all gwt-user, gwt-dev, and gwt-servlet (not to mention requestfactory, if you use it) jars are the version you intend them to be.
