Actually from my personal guess it is a lost viewstate because the jsf 
lifecycle is bypassed. The reason for pure jquery ajax probably being a 
little bit more responsive is the lack of the lifecycle handling.

I assume the you are in a jsf2 environment, if you look at the response
a jsf2 ajax call gives back there is always a viewstate variable 
returned in the response protocol which is generated from the server and 
if you bypass jsf this value either is lost or you might have an old 
value when you try to push the next jsf operation after the ajax call.

If you are in a JSF 1.x environment Trinidad I guess has something 
similar to keep the client in sync with the server viewstate.

I second that use jquery only for pure client operations and jqueries 
ajax only for the parts wich never touch jsf, if you want to go against 
jsf always use the plain jsf 2 jsf or whatever meta layer the underlying 
component lib provides.

Jquerys ajax is just a thin wrapper over the standard ajax mechanisms 
and does not have server side webframeworks in mind which have to deal 
with additional bookkeeping.
