Hi ZK team,

I have a problem:

I have a grid with combobox in each row. Some of them share comboitems. I have cases, when certain comboitem cant be selected in two comboboxes at the same time.

Thats why I need to make a validation after combobox selectedItem being changed. But when I trying to use something like that <combobox readonly="true" model="@load(each.suitableItemsList)" selecteditem="@bind(each.selectedDart)@validator('foo.bar.Validator')> and validation doesnt pass, binded item stays unchanged(thats correct) BUT selectedItem being changed on view(thats wrong). </p> <p>Is it conceived behaviour? Could you please give me any suggestions on how can I avoid this? Or how can I rollback item selection on my view?</p> <p>Thanks. </p> ">
