- the class is empty now and I want it to remain invalid-tab in this case. Is it because only one view / form is displayed and there is no form.editGuestUserFields1Form at all when I select different tab? In other words, do you think it's not possible with HTML to get what I want?

Ir occurs to me that you could avoid the whole problem by using named views in each tab ?
