Vaadin 7.2 - Textfield does not recognize input from Virtual Keyboard

I am using a Virtual Keyboard ( to for Textinput. Since i updated my project to Vaadin 7.2, the textfield does not longer recieve the entered Text even the entered Text is visible in the Textfields.

On the server side Textfield.getValue() returns an empty String, even there is a Text in the Textfield.

This bug was not in Vaadin version 7.1.15

i created a new ticket for this problem.

there is a small eclipse project attached to the ticket which demonstrates the problem.
