It is something that I asked for a long while ago.
I think that xwork interceptors are a little strange since they don't intercept JUST the execute method call. because the result is executed before the interceptor finishes.

so let me get this straight with PreResultListener would be able to have interceptors work before/after execute before the Result gets called?
that way we can have a flow like this using regular interceptors and also PreResultInterceptors:
before0 PreResultbefore1 PreResultbefore2 execute PreResultafter2 PreResultafter1 executeResult after0
am i understanding this correctly?

Yes, this is the intended behavior.
The issue is that Interceptors are stateless, so you can't do:
Intercept() -> before -> execute -> after Dispose()
Because your Interceptor can't keep request specific state to be disposed in another call...
I'm wondering if it would be a good idea to have an Observer pattern in here... PreResultListener.beforeResult(ActionInvocation invocation)... Then Interceptors that want to be notified before the Result could register with the ActionInvocation to have a callback... This shouldn't affect any of the current code, and would just allow for one more lifecycle point.. Thoughts?

Subject: [OS-webwork] Problems with code after actionInvocation.invoke()
I am currently having trouble with a custom interceptor. The Interceptor is supposed to determine which values to set on the ValueStack by the resultstring it receives from actionInvocation.invoke(). The problem is: Once actionInvocation.invoke() is executed the whole flow is executed, even the ServletDispatcherResult is executed and thus the JSP page is already loaded before my interceptor had a chance to modify some invocation result based values.
Is this the standard behaviour of Webwork 2.0 (latest CVS checkout) or should I file a bugreport in JIRA? If this is the standard behaviour the reason for an after() in AroundInterceptor is beyond my comprehension (other than possibly doing some clean-up and in that case it should be called something like dispose()).
Thanks in advance, /Daniel
