wicket - Ajax call not resets focus in page

I've a page , which contains a textbox . I've added AjaxFormComponentUpdatingBehavior to the textbox onchange , in which I update a few other form elements based on it's value .

As far as I understand , wicket would return to focus to the last focused component after the call . However , In this case , the focus isn't being returned to the component . The erroneous behavior exhibited happens only for the first ajax call made after the page is loaded , on subsequent calls it behaves fine.

The wicket-ajax debug log in case of the error looks like 

INFO: Response parsed. Now invoking steps...

INFO: returned focused element: [object HTMLInputElement]

INFO: returned focused element: null

INFO: Response processed successfully.

INFO: Invoking post-call handler(s)...

INFO: refocus last focused component not needed/allowed

Now I'm no wicket expert , but I have noticed that after every ajax call wicket logs the value of returned focused element twice , the second of which is logging null in this case .

I'd be grateful if anyone could enlighten me on what I could be doing wrong . Thanks for reading .

Here's my best guess as to what might be the problem.

Wicket keeps track of the last focused element is by setting a variable with the DOM id of the component .

If the DOM id of the component gets changed during the event (Wicket can do that , without you knowing :) ) , the last focused element reference in the front-end becomes invalid .
