Add a Validator on a transition screen for originalEstimate?

[Timothy Harris]

Having some problems validating originalEstimate field in a workflow transition screen. 

Using a Validation based on JQL query, which, I believe is provided by the script runner plugin.

The query is simple: "originalEstimate is not EMPTY"

Anybody created validator on a transition screen to require the entry of an Original Estimate?

This won't work if you're trying to do what I think you are, because the issue won't be indexed with the new value until it's committed.

Instead change to a "simple scripted validator", and use the condition:

issue.getOriginalEstimate()

Which is short for 

issue.getOriginalEstimate() != null && issue.getOriginalEstimate() != 0

Jamie, Thank you so much :-) I hadn't thought about the indexing!

Recognising that this answer was written a while ago.  It appears you now don't need to use Script Runner to perform this validation. You can add this validation directly in a Transition Validator. (Working Jira Cloud )

I saw issues that transitioned with 0m as estimation although we had this validator.
Any ideas why it's happening?
