Hi everyone,
I have a business rule with scope on my model-driven form (choosen one). The rule is very simple - when changing decision status to "Cancelled", user must fill the Comments field. Everything is fine - when I change the status of decision, error show on my screen, Comment field has the asterix and i can not safe the record :


But the strange think happens whe I click on this error - then the notification dissapear and now I can save my record what is not proper because this decision need to has comments (user justification).
I can extend scope to the whole entity and then I have a message :

But I need to this a little bit earlier - on my form. I am wondering why it doesn't work on my last stage of process, because I have the simillar business rules on previous stages and everything works fine (can not save the record before comments field is filled).
Did everyone has the same problem and can help me to explain it ? Thanks for all directions and informations.
