Components using an Alias bean are rendered when it's parent tabbedpane is not! This is causing a javax.faces.FacesException? (REPOST)

[Paul Spencer <pa...@apache.org>]

(MyFaces + Tomahawk both 1.1.4-SNAPSHOT and 1.1.5-SNAPSHOT)
I have defined an aliasBean in a tabbed pane.  If that tab is not the
current tab, the components that use the aliased bean are rendered even
though they are not displayed on the page.  This becomes a problem when
the rendering fails.

**
* The example below is simplified version of what I am trying to do.
**
The pages initially displays the tab "Summary Report" and none of the
radio button are selected. When I select the tab "Finance Report" and
select any of the radio buttons, I see the following:

1) The valueChangeAction is called.
2) The  exception "javax.faces.FacesException: Value is no String"
    is displayed.  In addition the error references the following
    components:
   {Component-Path :
     [Class: javax.faces.component.UIViewRoot,ViewId: /query.jsp]
     [Class:
org.apache.myfaces.custom.tabbedpane.HtmlPanelTabbedPane,Id: _idJsp1]
     [Class: org.apache.myfaces.custom.tabbedpane.HtmlPanelTab,Id: _idJsp2]
     [Class: javax.faces.component.html.HtmlForm,Id: SummaryForm]
     [Class: org.apache.myfaces.custom.aliasbean.AliasBean,Id: test_ab]
     [Class: javax.faces.component.UINamingContainer,Id: test]
     [Class: javax.faces.component.html.HtmlSelectOneRadio,Id: test_s1r]
   }



** JSP code

<t:panelTabbedPane>
  <t:panelTab label="Summary Report">
     <h:form id="SummaryForm">
       <t:aliasBean id="test_ab" alias="#{manager1}"
                    value="#{SummaryManager}">
         <f:subview id="test">
            <h:selectOneRadio id="test_s1r"
                    value="#{manager1.periodType}">
              <f:selectItem itemLabel="Month To Date" itemValue="mtd" />
              <f:selectItem itemLabel="Current Day" itemValue="now" />
            </h:selectOneRadio>
         </f:subview>
       </t:aliasBean>
     </h:form>
  </t:panelTab>
  <t:panelTab label="Finance Report">
     <h:form>
       <t:aliasBean alias="#{manager}"
                    value="#{financeManager}">
         <f:subview id="test">
            <h:selectOneRadio value="#{manager.periodType}"
                      valueChangeListener="#{manager.changePeriodType}"
                      onclick="submit();">
              <f:selectItem itemLabel="Month To Date" itemValue="mtd" />
              <f:selectItem itemLabel="Current Day" itemValue="now" />
            </h:selectOneRadio>
         </f:subview>
       </t:aliasBean>
     </h:form>
  </t:panelTab>
</t:panelTabbedPane>


Note: If the #{SummaryManager.periodType} is not null, every thing work
as expected :(


1) Is this a bug?

2) Suggested workarounds?
