I'm trying to create custom search module that will fit into the out-of-the-box Plone search functionality. I'm running into a permissions problem (which I believe is a Zope and not Plone issue). I get back a list of dictionary objects from my search method and I want to wrap those up in an object akin to the AbstractCatalogBrains object used by Zope. But when I use my own SearchWrapper class, an Unauthorized exception is raised telling me I don't have the right to use the methods of my SearchWrapper class. To summarize: (1) a python script calls a search method that returns a list of dictionaries (2) the list of dictionaries gets converted into a list of SearchWrapper objects (3) the search.pt (in Plone) tries to display the search results, but when it tries to use the methods/attributes of the SearchWrapper class (e.g. Title, getId(), getURL(), etc) it raises an Unauthorized exception. I've tried different strategies: defining SearchWrapper as a Product as well as putting it in the Extensions directory. Neither seemed to work. I guess my basic question is: how do I tell Zope that my SearchWrapper class is safe in the same way that the AbstractCatalogBrains is safe, since Zope is ok using the methods and attributes of search when it returns a list of ACB objects? (I'll just add: I did try to sub-clas AbstractCatalogBrains, but I ran into problems trying to define new attributes. I'm assuming ACB is defined (using __slots__ or something), such that you can't define new attributes on sub-classes. I'm quite new to Python and didn't have a lot of success figuring that one out.) Thanks in advance for your help! Francis
