I would do a kind of trick in your case. Send form elements 
#onchangePost, then put login button #onClickUpdate: aComponent. At the 
start of that component check self session lastRequest isAjaxRequest and 
if true, activate a login procedure, because you already have an 
username and password posts from form elements.

So, username and password will be Ajax posted and by clicking a submit 
button you update that whole component and because this is an Ajax 
update, a login will actually be done.

I hope that this helps you a bit...
