symfony framework forum: symfony 1.1 => propel:build-forms builds no forms with 2 databases

Hi guys,
I'm completely new to symfony. I need to access two databases and both models have built successfully. But when I try to generate a CRUD, I get the following error message:

symfony propel-generate-crud frontend teams Teams

Fatal error: Class 'TeamsForm' not found in /opt/lampp/htdocs/symfony/lib/generator/sfAdminGenerator.class.php on line 722

I then tried to build the Forms myself, by calling propel:build-forms which prints the following dump:

>> propel    generating form classes

I guess I've got something wrong with my propel.ini or my schemas.

Here are the corresponding files:

Could you please give me a hint, what I have done wrong? I couldn't find anything on the forums (maybe I'm to stupid to search properly ^^)
