"Page Expired" page with PatternDateConverter

[Hemant Shah]

 I am new to the Wicket framework and I hope I can get some help with a 
problem I am facing.

I am using version 1.4.12.
I am overriding the AjaxEditableLabel class and its overridden 
getConverter method is at follows:

    @Override
    public IConverter getConverter(Class type) {
        return new PatternDateConverter("MM/dd/yyyy", true);
    }

However, the first time in a session the component is updated, I get the 
"Page Expired" message.  The error results only when the getConverter 
method is called.

Note that this happens only the first time I access it in a session. If 
I go to the home page and from there back to the page which contains the 
component, it works without any problems.

I am not sure how to overcome this problem. I hope you guys can help. 
Thanks.
