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).

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?

Thanks.

Strange situation,

One thing you can do is call from your validator a global command to your vm. In the vm you do a notifyChanged of the selectedDart. (or more if you have multiple issues).

It is not the way it should be, it's a work around.

Greetz chill.
