I need to create a script to produce an error if you set an End Date before a Start Date

[James Breunig]

I have tried to create a Behavior for a field that creates an error and displays a message if I try to set an End Date before a Start Date. I've tried the script attached. It gives no script errors, but also does not work. This seems like a common thing, but I can't find a thread that has one that works

Hi @James Breunig ,

The script is attached to the Downtime Start field, which means, that it is executed, after the Downtime Start field is filled in. When you create the issue, you probably first fill in the Downtime Start field, then the validator is executed, but the Downtime End field is empty, so nothing happens, and then you fill in the Downtine End field, but there is no validator set.

Could it be the possible explanation?

So maybe you could add the second validator to the Downtime End field, because you want to do the check every time one of the fields is changed?

I also believe it is not neccessary to have all the imports in the script. It should work without them.

Hi @Hana Kučerová

I've copied the script above into a server-side script for Downtime End. I've tried changing the order I fill them in. Still appears not to work.

That's strange, it works for me :-(

Just quick check - did you setup mapping for the behaviour?

Wow! That was it! I didn't know you have to pick a specific issuetype or it would not work. Thank you!
