It doesn't really care what I use for id or title or meta_type--seems to throw an error on every combination I throw at it! Should I just try the newest ZClass stuff from CVS, or do i need other pieces?

Chris, I can't reproduce against the head of the 2.6 branch.
Here is what I did:

  - I created a product, 'Control_Panel/Products/Muldrow'.

  - In its 'manage_main', I selected 'ZClass' from the add list,
    and filled in:

    o Id:  Chris

    o Title:  Test Collector #783

    o Meta Type: Collector 762

    o Create constructor objects:  Checked

    o Selected:  [ OFS.File ]

When I clicked the "Add" button, I got a "normal" folder
listing of the newly-created ZClass' "Methods" tab.

The only checkin within the 'ZClasses' package since the 2.6.1b1
release was a fix to ensure quoting of the ZClass title (to
alleviate a potential cross-site scripting problem).  I can't
see how it would affect your ability to add a ZClass;  at most,
the changed template might prevent your viewing its contents
after creation.

Can you try with the "latest and greatest" from CVS?  Or post
the values you are using for ID / title / meta_type?

Some more info: This happens no matter what I attempt to subclass and no matter whether I check the boxes for standard Zope base classes or constructer objects. Basically, it occurs on any attempt to add a Zclass.

When I attempt to add a Zclass in any product, I get the following error:
<!--
<p>Traceback (innermost last):

I'm able to add a Zclass with no errors using an identical Data.fs on Zope 2.6.0.
