Hi,

I noticed this in CAS4.x and CAS5.x.  CAS is built on Spring Webflow, it 
should automatically prevent double submission, but on my CAS overlay, it 
does not.

After form submits (such as Login, Password Reset), if the action takes 
longer to complete, and user clicks again before the Post is completed, I 
see the 2nd call coming in while the first is still being executed. 

What am I missing?  How would CAS (or Spring Webflow) prevent double-submit 
out of box?

P.S., this is not about the browser refresh, which happens when form is 
submitted for the 2nd time  _AFTER_ the 1st POST completes.  Mine is about 
clicking the submit button very fast, you generate multiple execution into 
the same action, when it should only be one. 

Thx!
Yan
