[Zope-PTK] toolbox_actions from a Zclass product

[Istvan Vago]

Hello PTK gurus,

as I know ZClass-es and DTML much more than Python programming, so I
decided to implement a portal managed ZClass.
I choosed ZClass_for_CatalogAware and ZClass_for_PortalContent as base
classes. Everything is OK for it, I only have one problem. I can't
implement the toolbox_actions method. I tried creating a toolbox_action
method in the ZClass, but I wasn't succeed. From the mailing list I
know, toolbox_actions returns a tuple of dicitionaries with keys:
name, url, permissions, category. I used this DTML:

<dtml-return "{'name':'Edit', 'url':'editForm', 'permissions':[],
'category':'object'}">

but got Zope error with this Traceback:

Traceback (innermost last):

Any suggestion?
