Sorry, I disagree. You might have seveal thousand objects. So interactivity makes no sense.
Then you misunderstand what I meant. The python script in my interface would be called on every object of a given metatype automatically. What I am missing is something similar to the way it is don in a sql database. You add a column and every row has the new attribute. We cannot do this in zope, as the objects are in a hierachal structure. So usually you use ZopeFind() to find all objects of a given meta_type and then you do something similar to the small pythonscript example i included. But many who develop Python Products get confused over how to do this in the "canonical" way. So a small class like the one I tried to illustrate, would probably lessen the confusion. regards Max M
