I have a mandatory custom field. On create if I do not supply the value
then I get an error and the ticket is not created. Thats great. But lets
say that I supply the value “X” for this field on create and then later go
in to update the ticket and make the custom field empty. At the same time I
update some other fields and then try to save the changes. It saves all the
other fields and reverts back the value of this field to “X” and shows
I would like it to give an error instead and not save any of the values. Is
this possible and if so, how?
