oracle.adfinternal.view.faces.webapp.rich.RichWindowManagerFactory$WindowIdProviderAdapter cannot be cast to org.apache.myfaces.trinidad.event.WindowLifecycleListener

I was working on Build JDEVADF_12.1.2.0.0_GENERIC_130608.2330.6668

I create a simple ADF page and i tried to bind the action from the backing bean then i tried to deploy my code.

Every time i was getting this error.

I don't know the reason for this error and i dont have a justification for the fix but i will just tell you what i did to fix this issue.

I went to my web.xml and commented the following code

<!--filter-mapping>
<filter-name>trinidad</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping-->


After that i was able to get the required result.
And even if after that you are not able to get the result remove the filter selected.



This is not at all a fix but this has somehow worked in my case for a POC.
