I have a use case where a form should be submitted automatically when  
the view is rendered ( a textfield is already filled out by the app)  
can I use a hidden field and an observe\_field on it to detect when it  
has be changed or is there another way of doing it ???

thanks for you help

I could imagine something with

function onload() {  
formNAME.submit();  
}

and then
