But the form doesn't check ownership of the file and category, because of that we cant have user in back end that can edit files, the problem is that we need that the users won't have permissions to edit all the files and categories only the files and categories they need, and for that because they don't have permission to edit (because that cause they can edit everything not only in phoca download), we need to establish somewhere the permissions for that, due to the fact that the component is not integrated with the joomla 1.6 ACL (because if that will be true will be able to establish permission for each category and file for each user group for backed users), I'm searching for a solution that solve this

with a different view that doesn't use joomla 1.6 ACL.
The tables that use the component have in the case jos_phocadownload owner_id field that I think we can use to check the self edit permission and jos_phocadownload_categories has the uploaduserid, accesuserid and deleteuserid that I think can be used to check the permission to create edit and delete categories and files.
Because I'm not a php - joomla expert

I'm askin for help with this so I can know with files I must edit so I can solve this until the component support fully the joomla 1.6 ACL, if you help me with some clues maybe we can solve this fast and solve this problem that not only I have.
