Subject Re: Invoking action methods from jsp: parameter types
Date Fri, 06 Jun 2008 13:57:05 GMT
Well, I managed to solve this one. Ognl didn't actually pass the object
itself to the method, but rather an instance of
com.opensymphony.xwork2.util.CompoundRoot. I managed to get the object I
needed by using its peek() method.
