customize bugzilla fields & User Permissions & comments

[Khokhar]

I have some products and groups.

Client
Developer

Only Developer should able the create/edit the but
but Client should not able to edit the bug but they.

The following discussion was very helpful for me.

http://groups.google.com/group/netscape.public.mozilla.webtools/browse_thread/thread/98efcae88fe84d6d/51c8deb672402e09?lnk=gst&q=permissions+for+all+users#51c8deb672402e09


Answer:
----------------------------------

> Product A:

ReadCreateA: Entry/Mandatory/Mandatory/--
EditA: --/NA/NA/Canedit
Similar for Product B.

For this, you need to give editbugs privileges to developers. If you
want to restrict editbugs privileges in other products, you need to
set up a group they are *not* a member of as xx/xx/xx/Canedit for the
other products. In your particular setup, this is already covered by
the EditA and EditB groups.

(Works fine )
When I use the above guide , it works perfectly except posting
comments. I am getting following error while posting comment --> "You
are not permitted to edit bugs in product Product A"

but I want users of "Group UsersA" should not edit the bug (that is
fine) but must be able to post the comment.

What to do ?
