| i understand what its doing, thanks Gary
its a lot of code only to make things work as one would expect them to
work out of the box, right?
But originally there was another issue I wanted to solve. it is rather
portlet specific than related to Struts.
If you generate a link using the wps tags or the internal navloop how
would you manage to not only invoke the receiver portlets doView but its
actionPerformed similar to addAction on PortletURI. The parameter is
delivered to the struts action, but is there a way to append parameters
that the portal recognizes as portlet actions?
