without actually seeing your setup hard to say but i would start with:
- checking if the object perms do not override category perms
- checking if the tracker is categorized and if the category perms do not override globals
- checking if the field's visibility/edit is not limited to a group
OK... now I need help... ;-)
Using Tiki 6LTS, I have a tracker with a field of type=category.
On a wiki page, I'm using the TRACKER plugin to preset a form, which includes the category field as a checkbox selection.
When logged in as admin, everything works fine.
However, as anonymous, the value of the category checkbox is not saved (that is, when I review the submitted tracker/form later, as the admin, the field is blank — even though it is a "required" field and it was selected when the form was originally submitted).
Some sort of permissions issue, right? Well, I can't find it. I've given anonymous all the necessary (or so I thought) perms for creating trackers and adding items to the category.
Any help would be greatly appreciated...
