using frames and javascript
by David 05 Sep '01

05 Sep '01

I have a fully-functional (in IE 5x) frameset that uses javascript with rollovers, etc., and want to use it in Zope. Anything special I need to do or know about? I'm brand new at zope... (ok one or two weeks old) but I'm not a programmer, so be gentle :-) thanks CD

Overriding manage_properties in a ZClass
by Ronald L. Chichester 05 Sep '01

05 Sep '01

I have a ZClass where I want to use my own manage_properties dtml page. However, when I use manage_properties = DTMLFile('www/manage_editForm', globals()) and then manage_options=( {'label':'Properties', 'action':'manage_properties'} , ... ) The instance (which is derived from Folder) merely shows the standard Folder properties (e.g., title only). changing the 'action':'manage_editForm' doesn't work either. Hints, anyone? TIA, Ron

Since an object's attribute only springs into existence when they are actually assigned to (section 9.3.3 of the Python tutorial), the average object might not need get quite so large. Roger
