Aloha!

Is the Portlet MVC in 2.0-M1
(spring-framework-2.0-m1-with-dependencies-build.383-20051214.zip)
supposed to work?
My portlet application works with Portlet MVC as published in the
confluence wiki. But after switching to 2.0-M1 the portlet content is
not rendered anymore. There are no error messages, and the controllers
are processed correctly. Deploying the portlet sample application showed
the same effect (uisng Liferay 3.6.1).

BTW: I had to change my portlets to use
org.springframework.web.portlet.ModelAndView instead of
org.springframework.web.servlet.ModelAndView. What's the reason for the
new ModelAndView class?

Another issue is related to Liferay. It seems Liferay is creating Action
Requests to change the portlet window state. This means a portlet will
receive action requests even if it is not meant to handle these
explicitely.
The problem is that the default implementation of
handleRenderRequestInternal(ActionRequest, ActionResponse) in
AbstractController throws an Exception. To work in Liferay every
controller has to overload this method (same for render requests).
I propose to change the methods in AbstractController to just do nothing
(or maybe to issue a debug or warning message).
