I've three questions (but I'm making progress!): 1) In 2.2.5, how can I call a ZSQL method from a Python Method - I'm passing the method in as a parameter, and the furthest I get says "__call__ not defined". Do PythonScripts obivate the need for this? I assume I can just do this: for record in context.folder.subfolder.SQL_method(val1='a',val2='b'): # do stuff Does that work? 2) When calling a DTML method over XMLRPC, <dtml-in "SQL_method(username=AUTHENTICATED_USER)"> doesn't work, but <dtml-in "SQL_method(username=REQUEST.AUTHENTICATED_USER)"> does. Why? 3) Why aren't record values (the return of an SQL method) marshallable over XMLRPC. I get this: cannot marshal <extension class ExtensionClass at 70356ff4> objects Regards, Phil
