Actually, this is a problem in OGNL, because the version bundled with Struts 2.1.2 cannot handle objects with generifyed properties. This definitively sucks since it prevents a lot of code reuse, in my specific experience I had a similar implementation for a base ModelObject and an AbstractCrudAction but because of this error, it is not possible to generify these objects.
There is already a Jira issue about this situation: https://issues.apache.org/struts/browse/WW-2128 Regards, Carlos Luis Zúñiga Sibaja __________________________ [EMAIL PROTECTED] divide et impera...
