Use of JSTL/core tags screws up ViewScoped Bean

Question

I think I have run into a bug in Mojarra 2.1.0. Maybe I missed something but damned if I can see it.

I rely a lot of @ViewScoped beans to save state whilst the brows

This is a known "bug": issue 1665. It's a chicken-egg issue with regard to partial state saving.

In your case, however, you could also just use <ui:repeat>.

<ui:repeat value="#{testStuff.stuff}" var="x">
    <h:outputText value="#{x}" />
</ui:repeat>

Your best bet is to try to avoid JSTL tags when using @ViewScoped. The only alternative is to disable partial state saving by a context param in web.xml:

<context-param>
    <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
    <param-value>false</param-value>
</context-param>

But it makes the views more memory hogging.
