Decimal input - Data Validity not working

[Vlad_Roman]

My app has a Decimal input with 2 decimal digits and 0.5 step in one of it's forms. It has a "Valid if" constraint if the input value is greater than a certain value it will throw the given error message. Until a few days ago if u increased the value by clicking on the "+" button the error message was shown if it passed the maximum set value. Now it doesn't. The error is shown only if u try and save the form.

This is the constraint formula:  [_THIS] < [MAX VALUE].  "THIS" being the current input value and "MAX VALUE" is a column where the value is calculated.

 Any idea what happened? 

Thanks.
