Subject [jira] Updated: (WW-2754) Source code for GXP result
Date Sun, 13 Dec 2009 08:53:42 GMT


Benjamin McCann updated WW-2754:


Just about got this working.  I removed all the references to code that wasn't included so
that it compiles now.  I think I did something wrong upgrading to Struts 2 though because
I get the stack trace below when I try to visit my action that has a gxp result type.  There
was some code in the original submission that did something along the lines of "new OgnlValueStack(ActionContext.getValueStack())"
and that constructor wasn't available anymore, so I switched it to use the OgnlValueStackFactory.
 Maybe someone more familiar with Struts can take a look at section of AbstractGxp and see
what I did wrong.

java.lang.IllegalArgumentException: Wrapped type converter cannot be null
