[Zope] problem with 2.2.0b1

[Harald Ragger]

I just tried the new 2.2.0b1, and most imported things from my 2.1.6
installation are running fine, including all sql-methods.
But:
when I choose one sql-method from the management interface or try to add a
new one, i get the following error-message:

"Warning: There are no SQL database connections. You need to add a Zope SQL
database connection before you can use a Zope SQL Method. "

Thats funny, because I know, that the DB connection is up and running.

Any Idea?
