Attached test case that shows issue.

Steps:

• Load welcomeICEfaces.jsf
• Enter in some text to the input field.
• Tab out, exception is thrown

PartialSubmitValueBinding present only in icefaces-ee-compat.jar, so no question of "package+classname duplication."
Problem is caused by the use of <c:set>, not partial submit:
<c:set var="required" value="true" />
......
<ice:inputText ... required="#

" ... />
If we just use required="true", then everything works fine.
What exactly does <c:set> do behind the scenes?

Which version of mojarra is used for this test? There are various state saving problems prior to mojarra 2.1.8 that could lead to the Exception.

If you guys look at my jira I recently created:
ICE-8747 : FixViewState use of StateManager.getViewState(FC) disrupts state saving under MyFaces

You see that with MyFaces, FixViewState causes state saving to happen too early, in the middle of rendering. Presumably we temporarily put the PartialSubmitValueBinding objects in place, and intend to remove them before state saving occurs, but FixViewState messes that up.

I wasn't able to reproduce the issue cited with the test case. Can someone confirm that the behaviour is still a problem?

So, now that I add the accessible component library is in there, I do see the exception. However, I'm wondering how valid the page markup is:

<c:set var="required" value="true" />
<ice:form id="form">
<ice:inputText id="testIceVar" value="somevalue" required="#

to anything useful but I'm not sure why it only complains when the accessible library is present.

In the icefaces-ee-accessible.jar, at the bottom of the META-INF/faces-config.xml file there is the following:

    <!-- configuration taken from compat/components -->
    <ordering>
        <after>
            <name>ICEfacesCore</name>
        </after>
    </ordering>
    <lifecycle>
        <phase-listener>com.icesoft.faces.application.PartialSubmitPhaseListener</phase-listener>
    </lifecycle>
    <factory>
        <partial-view-context-factory>com.icesoft.faces.context.CompatDOMPartialViewContextFactory
        </partial-view-context-factory>
    </factory>

This duplicates what is already in icefaces-compat.jar. Not sure if the accessible library can work without the compat components or not but the double registration of the com.icesoft.faces.application.PartialSubmitPhaseListener seems to be the problem. If I remove that from the faces-config file, the problem goes away.

Yip, please go ahead and remove the PartialSubmitPhaseListener from the Accessible Comps lib. This is not required by accessible and would already be setup by Compat, which Accessible requires anyway.

I believe that this:
<c:set var="required" value="true" />
<ice:inputText required="#

" partialSubmit="true" />

Is just another way of doing this:
<ice:inputText value="required="#

" partialSubmit="true" />

Which is to test the case where the required property has a ValueExpression, and not just a simple Boolean value. This is because the bug is with the replacement faked ValueExpression not being Serializable, and not yet having been swapped with the real one when our code prematurely triggers state saving.

That makes sense. I retested putting everything back the way it was. Removing the duplicate PhaseListener "fixes" this particular problem.

Done. Error gone.
