Hello-- I'm having a problem with indirection. I have a form object that has a header method. I also have a DTML method called showForm: <dtml-var "form.header()"> The problem is that the name of the form object that I'm calling is variable. From all of the Zope docs and howtos, _[var] should allow you to do indirection. I'm putting the actual name of the form object as a parameter to showFormm so this should work: <dtml-var "_[form].header()"> But this gives me an AttributeError of __hash__ error with the following traceback: Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/local/zope/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: index_html) File /usr/local/zope/lib/python/DocumentTemplate/DT_String.py, line 540, in __call__ (Object: index_html) File /usr/local/zope/lib/python/DocumentTemplate/DT_Util.py, line 339, in eval (Object: showForm(form=dumbform)) (Info: showForm) File <string>, line 0, in ?
