Werner Punz commented on MYFACES-2762:
--------------------------------------

We had another issue with lost viewstates even in the old codebase which wa=
s fixed by the new javascripts, but it can be that this one is a new bug in=
troduced by the viewstate fixups.
Nevertheless the root cause of all this is mostly a spec leak
which mostly prevents cross form submits and generally multi form handling =
in a clean manner,
 which I already filed, but let me see if we can fix this issue as well. Cr=
oss form submits and especially this case should work.

> Is seems that handling of http://www.mail-archive.com/jsr-314-open@jcp.or=
g/msg00043.html (https://javaserverfaces-spec-public.dev.java.net/issues/sh=
ow_bug.cgi?id=3D790) is broken in current trunk. This example:
>         <h:form id=3D"form1">
>         </h:form>
>        =20
>         <h:form id=3D"form2">
>             <h:commandButton value=3D"AJAX Submit">
>                 <f:ajax render=3D"@all" />
>                 <f:setPropertyActionListener value=3D"#{true}" target=3D"=
#{viewScope.test}" />
>             </h:commandButton>
>         </h:form>
>         <h:outputText value=3D"#{viewScope.test}" />
> should produce output "true" with all clicks but it works only at first. =
Firebug shows that all javax.faces.ViewState elements are removed after fir=
st response. If I comment out first h:form it works as expected.
> Because this example works fine with 2.0.0 I think it a regression.
