I'm having an issue with the Dropdown Select of OutSystems UI.

If my combobox is not valid on the form and I have a Dropdown Select associated to that combobox, the border doesn't turn red at all.

Can someone help me?

Do you have custom CSS on your screen/theme/webblock/element?

No. If I try to apply a class in the ExtendedClass, I get a client exception.
