You can use "onchange" event to do that.
Yes, I tried to do that, but the bean recieves null on the ffield indicatted by the value attribute.
What do you think I must put in onchange to get autosaved facility?
I think you can try adding this:
<a4j:support event="onchange" />
Ok, Now it works. The proble is that I have replaced only the jars of the new version of richfaces, but not the tlds, so if I put the new tld distributed with the new version, alll works fine.
thanks in advance.
