Re: IllegalStateException from org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher
There's a couple of issues with this. First, a portlet only produces page fragments, you can't use , or tags. So you'll have to find another way to refresh the page. Second, the url-tag needs a specified action to produce a correct URL in a portlet environment (there's a JIRA ticket for using the executing action if no action is specified, but this hasn't been implemented yet). Try using instead. Nils-H On Jan 2, 2008 10:05 PM, Wanjun Wang <[EMAIL PROTECTED]> wrote: > > > Nils-H, > > I noticed some error in my struts-view.xml.

Re: IllegalStateException from org.apache.struts2.portlet.dispatcher.Jsr168Dispatcher
I have never tested the execute and wait stuff, so I don't really know how it works. But from reading the code for the interceptor, and reading the stack trace, I would guess that this happens because the default "wait" result is invoked and is not a result type that is supported in a portlet. You could try configuring a result for "wait" for the action explicitly. If you still have problems, please provide the relevant configuration snippets.
