Hello, I'm trying to add a new attribute to all objects of a certain meta_type on my site. These are objects that already exist and are already instantiated. But, no matter how I go about it, I always end up with the same end result: Error Type: TypeError Error Value: attribute-less object (assign or del) I've treid using portal_catalog search results, and then something like : setattr(a,'newporperty',''), but that gives me the error above. I also tried o.property = '', but that didn't help ... I also tried creating myobject = o.getObject() ... no go ... Then I found some examples on various web sites that use ZopeFind to locate their objects ... tried that, still no luck. What am I missing here? One thing, this is a custom object I added to the CMFDefault product, could that be part of the problem? This object otherwise works great within Zope and the CMF. The traceback output varies depending on how I try to go about it, but here is the lastest one: File Script (Python), line 14, in addPropertyToObjectType (Object: english) File /usr/local/Zope-2.5.0/lib/python/RestrictedPython/Guards.py, line 107, in guarded_setattr (Object: density) File /usr/local/Zope-2.5.0/lib/python/RestrictedPython/Guards.py, line 72, in handler "English" is a Portal Folder, "density" is one of my custom objects .... Help ? Thanks in advance, J.F.
