BrowserWindowOpener is working with Shorcutkeys


This is related to the issue i am facing with BrowserWindowOpener. I am using vaadin 7.5.8, I have extend/attached the BrowserWindowOpener in
Button and when i click the button the UI is getting displayed in a separate browser window. But when I attach the shorcut listener in the view/page level and invoking the BrowserWindowOpener in a method is not display the UI. Kindly share me what i am doing wrong.
Further, i have tried calling the method in the shorcut handleAction method, unfortunately this is also not working.
Please share your comments ASAP.
