Description

I have a Button that shows a JS alert and then executes an AJAX call.
It works fine under Firefox 2, but fails under IE7.. The alert appears, I click "ok" and then I get the "Initiating Ajax GET request..." inside "WICKET AJAX DEBUG", but it doesn't reach my serverside handler.
After clicking "ok", in the bottom-left corner of the window appears a javascript error: "Invalid procedure call or argument", line 849, code 0.

I'll add a quickstart and a patch in a moment.
