Duplicate ResourceEvent.ERROR with ResourceManager

Question

Hello, I am working with resource modules and I believe I am doing everything by the book. However, when setting up error handling I ran into an interesting issue where I get two ResourceEvent.ERROR events when I try to load a nonexistant resource module.
Running the following code I get output of:
[ResourceManagerService.changeLocale]
[ResourceManagerService.addResourceEventHandlers]
[ResourceManagerService.onResourceModuleErrorHandler]
[ResourceManagerService.onResourceModuleErrorHandler]
If I remove the event handlers after the first ResourceEvent.ERROR event I get a runtime error "Error: Unable to load resource module from locale/es_ES_ResourceModule.swf " .
Is there something wrong with this code or possibly ResourceManagerImpl.as?  I am using FlashBuilder 4 and Flex SDK 4.1.0 build 16076. Thanks in advance for your help.

Hi ,
        Even i got same error, but to overcome this i have implemented the patch by the following steps.
1. i have copied the ResourceManagerImpl.as to local  "src/mx/resources/".
2. i have copied from C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\projects\framework\src\mx\core\version.as to "src/mx/core"
3.Open the locale ResourceManagerImpl.asand comment the
     moduleInfo.addEventListener(
           ModuleEvent.ERROR, moduleInfo_errorHandler, false, 0, true);
   lines in ResourceEventDispatcher function then try it.
For me this one working fine.
Thanks
