Validation issue

[Hyperbytes]

I think we can be pretty sure that this is not a bug as this is a well tried and tested component.

Maybe this thread may help as it discusses similar issues. If not we need more information to diagnose the problem.

"Check if a Database Record Already Exists" not showing error message

I have followed the tutorial, and have entered the field name in Linked Field (UserName). The action is working properly but the error does not show when username exists. I have tried with and without validation on the form field. It is a txt input. Any help or ideas on where to look would be helpful.
