You need to inherit from Folder as well. This one bit me last week. :-|

This doesn't work. Can anyone tell me why this might be happening????? I'm really starting to think ZClasses are just a complete waste of time.

I think what is happening is the following: Some objects think of themselves as 'methods'. If you ask them for this(), they will report their container object.

Other objects, like folder, report themselves when asked for this().

If you are inheriting from multiple baseclasses, the order will be significant. Try making folder the first object in the list you inherit from. If this doesn't work, try making it the last (I don't know if the top of the list or the bottom will take precedance).

I have yet to try this however isn't there a conflict here between ZCatalogAware. I thought that ZCatalogAware had to be the first to be inherited?
