I am experiencing the exact same problem ever since I moved to struts 2.1.6.
This was not a problem in struts 2.0.14, and in fact, we've stayed with struts 2.0.14 for this very reason.

We have struts.xml set up so that the portlet package extends struts-portlet-default and the normal actions extend struts-default. The problem manifests even if all we do is add the portlet-plugin jar into the WEB-INF/lib directory and do no other setup of portlets. So there seems to be something in the portlet plugin which is affecting normal action functionality. Iain.
