One fundamental question

[Anjali Abraham]

Hi All,
            I have in my html page the code like this:
<form jwcid="XXXX" name="YYY" onSubmit="check();">
 
When I had run this page and seen the "view source" of the page, I havnt
found the onSubmit="javascript:check(); method in my form tag. Why??????
 
I got this doubt since I had given only an alert in that javascript but that
method itself didn't get called. Don't know why???
 
Please can anybody explain me why tapestry ignores this??????
Please respond,
Thanks in advance,
 
Regards,
Anjali
