struts bridge submits twice
We are having an issue with the struts portals bridge, where a submit
is trying to go through the action class twice. As soon as the action
is completed and the forward happens, the action is invoked again.
Has anyone else seen this? Does anyone have any tips?
Thanks,
-- Jeff

This has been solved by Jeff himself, he mailed me directly.
The solution is to define the PortletRequestProcessor as controller in the struts-config file:
<controller pagePattern="$M$P"
inputForward="true"
processorClass="org.apache.portals.bridges.struts.PortletRequestProcessor"/>
Without this, the Struts framework uses its own PortletRequestProcessor under certain
conditions (not always) with as result that the StrutsPorlet isn't informed about the end
state of the actionRequest. Then, it will use the original Struts page URL for the renderRequest
again, leading to the double processing of the action.
I'm currently working on some improvements and enhancements for the Struts Bridge which
I hope to commit in a few days or a week or so. I will then also provide proper usage documentation,
including a checklist and instructions to enable existing Struts applications as portlets.
Regards, Ate

Here are the debug statements showing the progression through the
struts bridge. Sorry to reply to my own message, but I wanted to
relay this extra information. It looks like the action is processed
once for requestType ACTION and another time for requestType VIEW, but
the action should really only be processed once.
