Submitting form in onchange event

[Upayavira]

I'd like to have an on-change event actually submit the form, rather 
than just execute the <wd:on-value-changed> javascript code.

How can I do this?

Otherwise, the on-value-changed javascript doesn't have access to the 
local variables of the main flowscript, which I need to repopulate my 
form for redisplay. (I know I can get hold of the bizObject from the 
request attribute, but it all seems rather hard work to use it there. 
There's an elegance I'm missing).

Thanks, Upayavira
