Background:
It used to be that when processing an Ajax response on the client, all
forms in the view
would get updated with the view state from the server (which had it's own
set of portlet
related issues). Before the specification went final it was decided that
only the submitting form should have it's view state updated from the
server.
Problem:
Consider the case where there are multiple forms in the view, and one of
the forms
is a partial render target. So here, "form1" is an Ajax render target:
<h:form id="form1">
<h:commandButton value="Should be postback" id="button1"/>
</h:form>
<h:form id="form2">
<h:commandButton value="Rerender form1" id="button2">
<f:ajax render=":form1"/>
</h:commandButton>
</h:form>
In this scenario, "form1" is missing the view state identifier causing a
"non postback" when "button1" is clicked.
-----------------------
I think this could get by as an errata for the MR, as we would need to
include additional
spec language.
+1. We need to be very sensitive about these "ghost clicks" because that
issue has really spurned JSF users in the past.
