Hi,
I am using the pageflow and normal s:decorate with ajax pattern as in the examples.
On the onblur event huge amounts of code seems to execute (seen in server.log) which takes so long that subsequest onblur events gets a concurrent problem

| summary=(The conversation ended, timed out or was processing another request), detail=(The conversation ended, timed out or was processing another request)
Here is some of the logs from server.log generated on a single onblur ajax event.

This single ajax onblur request took 721ms.
It seems that Seam needs to work far to hard during the ajax request. Going to the bpm hundreds of times instantiating components hundreds of time etc.
I note that the dvd example does not use ajax.
Is this a know issue?
I am using seam-2.0.0.GA and jboss-4.2.2.GA
Cheers
Pieter
