Issue : 

Currently, when we add a validator to a transition and when the issue did not comply with the validator specified, it will display each the error one by one. (ie. it will display first field which did not comply and once that is resolved, it will display the second field that did not comply and so on.) which is time consuming and tedious.

References : 

In a scenario, where I added validator on fields Description, Due Date and Attachment as required before transitioning to the status. 

We get an error as below : (when all the 3 are not entered) 

We get an error as below : (when description and due date is entered)

Suggestion : 

It would be good if we get the 3 field in the same error window rather than having them separately after completing one.
