ComplexForm and Validation required not showing

Vaadin 6 / 7 / 8 Framework Data Binding

Hi

I created simple application and I have problem that in Form where Fields are displayed on different tabs and when Required field is not filled then on button click (form.commit()) is not showing notification on bottom of the form with proper field’s ReuqiredError text.

I thought that maybe I made some mistake in FormFieldFactory implementation but I created simple form and everything works as expected.

Image shows the problem:

Source code of application is in here:
Application
 - HelloWorld_Validation.rar file (eclipse project - I’m using hsqldb so only import and should work)

I also wonder how to show user on which tab is field that was incorrectly filled.

Best regards.


EDIT:

I created repo on github: [Whole Eclipse project - Windows]

I found a soluction. I didn’t add Form to Window only TabSheet that was the problem. After add Form also to Window notification on commit shows as expected.
I also make that is showing error icon on tab and selecting tab where is invalid field.

On github is new version.
