[Springframework-developer] com.liferay.portlet.ActionResponseImpl cannot be cast to javax.portlet.RenderResponse

[Jan N. <jan...@gm...>]

I compiled and deployed the "petportal' portlets from Spring 2.5 in
LifeRay 4.3.3. When I click on "remove" for "Polly", I get the
following error:

java.lang.ClassCastException: com.liferay.portlet.ActionResponseImpl

It appears that AnnotationMethodHandlerAdapter at 174 assumes that the
action response is a javax.portlet.RenderResponse if the request is a
javax.portlet.RenderRequest. In this case, that assumption is not
true. Perhaps because of the multi-part resolver?

Any ideas?
