Hi all, I am trying to produce a product with a python script which installs a configured ZCatalog. I can add the ZCatalog OK, but configuring is giving me problems. In my ZCatalog derived class __init__ I have tried to build the meta-data table: self.manage_addColumn('blah') - doesn't work and for properties: self.manage_addProperty('prop', 'value', 'string') self.manage_changeProperties(prop='value') these don't work either. I neither get error messages nor results. I am not clear whether I am dealing with the regular PropertyManager or with the zclass variety. For the manage_addColumn problem, maybe I can't do this in the __init__. If this is the case how do I set the meta-data automatically? Any pointers would be greatly appreciated. TIA
