Hello David,

You didn't describe what the user-defined condition does, but I can 
guess what's happening. I'm assuming that the problem occurs when a 
ticket is updated in the web interface, from a screen that allows 
custom fields to be updated.

When you submit the form, the CF value on the screen is blank. The 
scrip changes the value to 'James Wot'. Then the values submitted 
from the form are processed - RT sees that the current CF value is 
'James Wot' and that the submitted value is null. It interprets this 
as a deletion.
