[Zope] List attribute inside of a product...

[Jeff Ross]

I'm writing a product that needs a list of items inside it, e.g ['abc',
'456', '243'].

The list stays intact if the server is up. But if I shutdown and restart,
the list is cleared again.

Here's some of my code:

class Store(Folder.Folder, PortalContent, DefaultDublinCoreImpl):
    """ Store Class """

    meta_type = 'Store'
    _isDiscussable = 1
    icon = PortalContent.icon
    categoryList = []

    def manage_addCategory(self, id, title, REQUEST = None):
        self.categoryList.append(id)

Is this the reason my list is getting reset to empty on restart? I don't
understand. If I have a text attribute and set it to empty in the class
code, then it's fine. I get my saved attribute. But my list is blown away.
