We're currently porting our GlassFish 3.2.1.x webapp to JBoss EAP 6.4.6, but we're getting a rather strange exception with a page that contains (shortened):
<h:panelGroup id="absence-panel"
layout="block"
styleClass="bx-accordion-correction">
<h:panelGroup layout="block"
styleClass="left-button-panel">
<p:commandButton id="add-absence-btn"

actionListener="#{employeeAbsenceManager.add}"
immediate="true"
process="@this"
update="absence-panel
:content-form:employee-navigation
:content-form:msgs
:content-form:growl"
oncomplete="scrollContentToSubPanel(this);"
disabled="#{employeeManager.readOnly or employeeAbsenceManager.mode eq 'ADD' or employeeAbsenceManager.mode eq 'EDIT'}"
styleClass="bx-first-button">
<p:resetInput target=":content-form:accor-panel:absence-subpanel" />
</p:commandButton>
</h:panelGroup>
<p:blockUI block="absence-dir-list"

<p:dataTable id="absence-dir-list"

selectionMode="single"

rowStyleClass="#{abs eq employeeAbsenceManager.selectedEntity ? 'ui-state-highlight' : null}"

styleClass="bx-datatable-header-hidden mt-10px datatable-content-scrolling max-width-1300">

</p:dataTable>
<ui:include src="absenceSubPanel.xhtml" />
<h:panelGroup id="absences-validator">
<o:validateMultiple components="absence-type absence-begin-date #{employeeAbsenceManager.uniqueConstraintWithRemarks ? 'absence-remarks' : ''}"
validator="#{employeeAbsenceManager.validateUniqueAbsences}"
message="#{employeeAbsenceManager.uniqueConstraintWithRemarks ?
msg['entity.absence.notUniqueMessageWithRemarks'] :
msg['entity.absence.notUniqueMessageWithoutRemarks']}" />
</h:panelGroup>
</h:panelGroup>
The <ui:include src="absenceSubPanel.xhtml" /> contains the <o:validateMultiple>'s components. It's the sub panel for an absence (e.g. vacation, sickness, some educational measure for an employee).
The remarks are conditional depending on some customer setting whether they have absences with or without mandatory remarks.
We get the following exception:

OmniFaces version is 1.7. We're also using PrimeFaces 3.5.28 (the last of the 3.5 tree) and Seam Faces 3.2.0.
Any ideas what could cause this and how to fix it?
Thanks
We have just been able to get rid of the exception by putting the following into the
faces-config.xmlfile:Is there any explanation/assumption for why this is the remedy?
