Symptoms
You are trying to use ADF Faces Dynamic Table components (dynamic:table) together with an af:panelCollection:
...
<af:document title="dynamicTable-panelCollection.jspx" id="d1">
<af:messages id="m1"/>
<af:form id="f1">
<af:panelCollection id="pc1">
<f:facet name="menus"/>
<f:facet name="toolbar"/>
<f:facet name="statusbar"/>
<dynamic:table value="#{bindings.TestTableDataTypeIterator}" id="t2"/>
...
If you wrap the dynamic table in a panelCollection, you get a NullPointerException when running the page:
...
<LifecycleImpl>
<_handleException> ADF_FACES-60098:Faces lifecycle receives unhandled exceptions in phase RENDER_RESPONSE 6

...There is no problem when using a standard ADF Faces Table component wrapped in a panelCollection:...
<af:panelCollection id="pc1">
<f:facet name="menus"/>
<f:facet name="toolbar"/>
<f:facet name="statusbar"/>
<af:table value="#{bindings.TestTableDataType.collectionModel}" var="row"
... id="t1">
<af:column sortProperty="#{bindings.TestTableDataType.hints.FirstName.name}" filterable="true"
... id="c1">
<af:outputText value="#{row.FirstName}" id="ot1"/>
</af:column>
...Same when the page contains an ADF Faces Dynamic Table component without panelCollection:
...
<af:document title="test2-dyntable.jspx" id="d1">
<af:messages id="m1"/>
<af:form id="f1">
<dynamic:table value="#{bindings.TestTableDataTypeIterator}" id="t2"/>
