I do not want people start an issue without a remaining estimate. So the Transistion should perform a validation. But there is no option to validate these field "> 0"? I have with "Field Required Validator" the possibility to check if it is empty. But i need empty OR 0.
At the conditions there is the possibility with "Value Field". But that does not help. Now the button for the transition is missing but nobody knows why.
I need the same check at validation to give some feedback of the field is empty or 0.
Is there a solution?
