How to check date customfield for null value in transition screen?

[Edvin Beqari]

I have a date field that must not be null - however, I cannot make it required because it is in a transition screen. 

I have tried some regex but no luck. What is the proper way to do this?

Thanks

Hi Edvin,

Try placing a Validator on the transition to make the field mandatory. It should not fire until you have saved the value on the Transition screen.

Hi @Edvin Beqari  as mentioned by John,Proper way is to make the field mandatory on Transition screen, you need to add Field Required Validator in workflow. Select field put error message > Publish. it's the best simple solution to make field mandatory on transition.
