The product didn't have a 'broken' icon, it just didn't have any of the 
subobjects.  Normally I would have the product name and three items in the 
product which corresponded to the three ZClasses defined in the 
product.  When the python code is bad I have no ZClass subobjects and any 
instances have the broken icon.  However, I don't see a management tab 
anywhere and the source html doesn't tell me anything.  Right now the way I 
"solved" my problem is to open the python interpreter and "import" my 
python base class.  That way I can see syntax error messages.  It seems 
like there must be a better way.

I believe that would work for adding DTML Methods, but when I want to add 
an instance of my ZClass I do something like this in DTML code:

<dtml-call "FooClass_add(_.None, _, NoRedir=1)">

what is the equivalent Python code?  The "_" isn't understood as an 
attribute and if I replaced "_" with self then None isn't found.

Thanks for your help.
