[Zope] a product with external methods

[Jerome Alet]

Hi,

1st question:

I'm currently creating a ZClass based product which includes some external
methods.

If I want to distribute this product, do I have to distribute my product
AND my external methods for it to work correctly elsewhere, or just
distributing the product is sufficient ? 

2nd question about ZCatalog and Zope 2.1.6:

When I instanciate a folderish ZClass of my own, I want to automatically
create a ZCatalog instance, then I add the following line to MyZClass_add
method:

<dtml-call "manage_addZCatalog('Catalog', 'My Catalog')">

and when I create an instance of my class I've got the following
NameError :

-->

If I don't call manage_addZCAtalog in my add method but instead add the
ZCatalog from Zope management interface it works fine.

I think I've called this method correctly according to the ZQR, so I can't
understand why it doesn't work.

I've searched on this list archives on egroups about "adding ZCatalog" or
"add ZCatalog" and I've not found anything useful.

then I've searched for manage_addZCatalog and I've applied the patch sent
by Dieter Maurer on May 28th to ZCatalog.py and restarted Zope but with no
luck. 

please could someone help me ?

thanks in advance.
