I've created a simple validation script (for this test) which stops an issue/record transition if the original-estimate (time tracking fields) value is greater than 2 hours. It's implemented as a Validator on my custom Workflow and is coded as:
issue.originalEstimate <= 7200
Problem 1, I set the associated Script Validator Field as Original Estimate and make the User confirm the Estimate via a Transition Screen. Upon click the associated button the validation fires and when the condition above returns false nothing occurs on the UI but the atlassian-jira.log captures a series of errors (shown below). Entering a valid estimate (<2hrs) seems the transition complete as expected. Note, if I leave the Script Validator Field set to <blank> the expected functionality works, i.e. either an error message is displayed or the transitions occurs when correct. Any ideas?
Problem 2, I'd like this validation to not reply on a transition screen but when no screen is specified the error message I added is displayed in a dialog but also a message about "an illegal workflow operation" and "contacting the Jira admin" (see below) How do I get rid of these messages. Note, this dialog/validation also only works when the Script Validator Field is set to <Blank>
The dialog message
Assignee does not have enough free time
It seems that you have tried to perform an illegal workflow operation.
If you think this message is wrong, please contact your Jira administrators.
