Java HtmlUnit onchange event not fired

Question

I use HtmlUnit to fill form. I have a select SELECT_A. After selecting option the additional elements must appear in the page. But it's not working! I simulate Firefox 3.6.

What do you think?

I tried to use NicelyResynchronizingAjaxController() but it does not help.

One note: fireEvent should be called with "change" parameter, not "onchange". Or fireEvent(Event.TYPE_CHANGE); is even better.
