hmmm... what are the args to the method and how are you calling it? from
your spelling i assume you mean a web PythonMethod..


if your zclass is an objectmanager why not
<dtml-var "'method1' in self.objectIds(['DTML Methods'])">


anyways, i tried your example and it worked fine for me. i tried it with
a zclass whose only base class was dtml doc.

my pythonmethod 
accepted the object as an arg.

body
return hasattr(ob, 'method1')

returned the correct results. 1
