[rt-users] Locking up Custom Fields

[Mario Gomide]

Hello list!!!

I have an RT 3.6.1 installation, and RT works fine for me.

I was hopping someone could help me out on this one:
I have a couple of Custom Fields that must be filled up on the ticket 
creation BUT after that, they MUST NOT be changed! In other words, these 
specific CF must become read-only, uneditable, locked, disabled or 
whatever (since it still shows up on the screen), only after creation.

I've tried some javascripting but I'm not getting it. I know I can (as I 
already have done this) lock a given CF on the creation page, but not on 
the Modify or Jumbo pages.

Hope to hear from you experts soon!!
Thanks a lot!
