Automatic generating a slug fails if editor has no permission
A slug field only gets automaticly generated if the user has permission to edit the field.
There may be situations where a redacteur should not have permission to change the url, but has to be able to create a new record though.
This will inevitable lead to a error due to the missing slug for the record.
Only way to handle this is to use a tca hook generating the slug by yourself.
Should'nt it be possible to let a slug be generated even though the user has no edit permission, or would this be against the concept of the TYPO3 permissions?
