Default resource function is not always set

Minor issue again, perhaps somewhat related to my previous issue on users / resources:

If a resource is created via the 'User ' menu, with 'is a resource' checked, there is no "main function" selected by default.
- If you go to the Resource menu, it appears as though a main function had been set, but it is only in the display, and no in the DB.



- When creating an assignment on an Activity, and selecting the resource in question, there is no "function" filled in by default , and therefore one needs to be set manually.



If you do go to menu Resource and save the resource, the main function does get set correctly. However it is odd that the function appears to be already filled in, while in the DB it is empty.
