Werner Punz commented on MYFACES-2762:
--------------------------------------
We had another issue with lost viewstates even in the old codebase which was
fixed by the new javascripts, but it can be that this one is a new bug
introduced 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. Cross
form submits and especially this case should work.
> Handling mutiple h:form and AJAX is broken

> URL: https://issues.apache.org/jira/browse/MYFACES-2762
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.1-SNAPSHOT
> Environment: myfaces current trunk (19.6.2010)
> Reporter: Martin Kočí

> Is seems that handling of

> (https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=790)
> is broken in current trunk. This example:
> <h:form id="form1">
> </h:form>
>
> <h:form id="form2">
> <h:commandButton value="AJAX Submit">
> <f:ajax render="@all" />
> <f:setPropertyActionListener value="#{true}"
> target="#{viewScope.test}" />
> </h:commandButton>
> </h:form>
> <h:outputText value="#{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 first
> 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.
