(Newbie stops, wipes pieces of wall from forehead, and asks for help.)
I'm stumped trying to use a Script (Python) to change the properties of a sequence of Zope objects.
Here's the problem: certain objects (simple folderish objects of my 'Cable Channel' ZClass) have a property called 'categories' that needs to be in the form of a Python *list*. In many instances, however, the property was saved as a *string*. (For more detail, see my January 6 post "Solution for 'in requires character as left operand' error".)
In my Script (Python), I've been successful identifying the problem objects and retrieving from them their 'categories' string. Also, I can convert the string into a "singleton" list. Then I hit problems.
I want to iterate over these objects, calling a method that will change each one's 'categories' property. Hell if I can do this!
Are you trying to change property types? You can't do that with changeProperies. You'll need to remove the property then add it back with the correct type. Properties are typed even though python variables aren't.
