I face an issue with Bandbox used in a MVVM form with a "no empty" constraint.
How to reproduce:
- Open page
- Press at first save - the standard "no empty" error popup appears
- Select an item in the bandbox
- Press save again - popup appears again
First I saw that with Firefox. Now with simplifying the example it appears less and less often, sometimes only in debugger.
Then I tried with Chrome and there it always happens.
The reason seems to be an ErrorEvent which is still sent by the client.
I hope you also see that behavior.
