Subject [Trinidad] Server Exception during PPR
Date Fri, 29 Feb 2008 22:56:00 GMT

I'm trying to test out the Trinidad dialog framework (which seems quite 
simple to work with from the documentation).

What does the "Server Exception during PPR" and associated js alert mean?

The stack trace below suggests that the PPR request cannot handle 
calling a particular action listener. The bean is defined in request 
scope with the appropriate name, the method with the correct signature 
is there. Both of these values are unchanged during the port to Trinidad 
so I can guarantee that there is no naming issues. but there is no 
indication of what is actually going wrong. I can pretty much be sure 
that it is a 'lookup' issue of sorts since the actual method which is 
supposed to be called does nothing but return a string literal (it never 
actually gets called though).
