Issue description:

When entering text in the inputText, the request is sent, but the value is never set in the model. This only happens when you add something beneath the panelGroup. In the attached example it is the letter 't'. The panelGroup component is somehow lost in the restore view phase, the value is then not set in the apply request phase. This bug prevents usage of two consecutive panelGroups in a cellEditor.

To reproduce use the application attached to this ticket.

Editable data table source:

<ace:dataTable id="carTable"
                                    value="#{dataTableRowEditing.cars}"
                                    var="car">
               
                <ace:column id="name" headerText="Name">
                    <ace:cellEditor>
                        <f:facet name="output">
                            <h:outputText id="nameCell" value="#{car.name}"/>
                        </f:facet>
                        <f:facet name="input">
                           <h:panelGroup id="nameInput_pg">
<h:inputText id="nameInput" value="#{car.name}">
<ace:ajax execute="nameInput" render="nameInput_pg" />
</h:inputText>
                            </h:panelGroup>
                            <!-- remove this to get nameInput working -->
                            t
                        </f:facet>
                    </ace:cellEditor>
               </ace:column>
               <ace:column id="chassis" headerText="Chassis">
                    ....
               </ace:column>
               <ace:column id="weight" headerText="Weight (lbs)">
                    ....
               </ace:column>
               
               <ace:column id="options" headerText="Options">
                   <ace:rowEditor id="editor"/>
               </ace:column>
            </ace:dataTable>
