<s:set name="DynamicCodeType"
value="@com.whatever.myactioncl...@getcodetype(p.myInteger)'"/>
will work iff, static calls are enabled for OGNL, and "p" is a field
of the object on top of the stack, which I doubt, it should be
something like:
<s:set name="DynamicCodeType"
value="@com.whatever.myactioncl...@getcodetype(#p.myInteger)'"/>
assuming that "p" is in the stack pointing to your person object.
