I guess many refactorings happens in xwork (possibly to fix invalid methods ?) , especially in CompoundRootAccessor, and my current code is not working. The following example doesnt work anymore : stack.findValue("format(myDate)"). The error comes from the fact that the (Object[] objects ) argument passed to the CompoundRootAccessor.callMethod(...) is an array of size 1 containing a null object. Thus, the getArgTypes(objects) throws a NPE. Hope it can help. Richard.
