[Zope] Data.fs gone crazy

[Sebastien Bigaret]

        Tom,

  That problem bit me a few times already... I do not have an explanation for
that, except that for some reason, the Data.fs can get corrupted when you
uninstall a Product (no kidding ;) --anyway, according to my own experience it
seems to only happen with python-based products, not with ZClass.

  I usually solve the problem by following these steps:
1. export everything you'll need to 'rebuild' the Data.fs
2. stop zope
3. move the Data.fs elsewhere (I really mean 'move it', not delete: it's sooo
easy to forget to export some important stuff...)
4. restart zope --it build a brand new Data.fs
5. import all previously exported stuff

  ...and that's it. Anyway, I am also interested in learning a quicker way to
circumvent this problem --and whether it is a bug or not...

        Hope this helps,
                                Big.
