From my analysis on Omnifaces documentations, I guess that, the exception is due to an attribute called ATTRIBUTE_ERROR_EXCEPTION in HttpServletRequest object. But it should have been removed as I am using the FullAjaxExceptionHandler#handle() from omnifaces.
Events.addCallbackAfterPhaseListener(PhaseId.RENDER_RESPONSE, new Callback.Void() {
@Override
public void invoke() {
request.removeAttribute(ATTRIBUTE_ERROR_EXCEPTION);
}
});
The above piece of code didn't removed that attribute.
Can I remove that attribute to get rid of that error? What is the main purpose of that attribute? and How to overcome the java.lang.IllegalStateException: in this scenario?
