AHhh okey thank you a looot , So i can create a new module test3 and Add : "depends" : ["test1", "test2"], ... Is that it ?

Yes, or in the __openerp__.py file for module test1, use "depends" : ["test2"] - then you don't need a third module.

Oki , thank you :)

when i tried this , i got the following error : Error

You try to install module 'test1' that depends on module 'test2'. But the latter module is not available in your system.

Then check that module test2 is available in the addons path - OpenERP can't find it.

actually the module test2 is in the addons directory ... Do i have to make anyother changes a part from the depends on the Depands in __openerp__.py??
