Objet : MasterDetail datatable, toggle all rows expanded, save state, 
detailStamp

Hello,

I am pretty new to JSF and MyFaces. I managed to use the master-detail feature 
of the extended data table, and it works fine, except for 2 things :

First, Is it possible to set the initial state of the table to all rows 
expanded (currentDetailExpanded=true) ?

I found related threads e.g. here
http://www.mail-archive.com/users@myfaces.apache.org/msg31418.html and here 
http://www.mail-archive.com/users@myfaces.apache.org/msg31509.html
but no real answer. Anybody can help with that ?


Secondly, is it possible to store the state of the table so that when I go to 
another page (e.g. edition of one of the entities managed in the table or a new 
one) and then go back to the table, the rows that were expanded still are 
expanded ? (something similar to the technique used for storing the state of 
the scrolling here maybe :
http://wiki.apache.org/myfaces/ManagingDataScrollerPage?highlight=%28dat
ascroller%29)

I am working with MyFaces 1.1.4 and Tomahawk 1.1.5 snapshot.

And finally here is my code for the table :

<t:dataTable
        headerClass="standardTable_Header"
        footerClass="standardTable_Header"
        rowClasses="standardTable_Row2"
        styleClass="standardTable"
        id="domainsDataTable"
        width="800px"
        align="left"
        border="0"
        cellspacing="2"
        cellpadding="2"
        var="domain"
        rows="10"
        preserveDataModel="true"
        rendered="true"
        value="#{domainsList.domains}"
        varDetailToggler="domainsDetailToggler"
        >
        

        <t:column width="20px">
                        <h:commandButton
        
rendered="#{domainsDetailToggler.currentDetailExpanded}"
        
action="#{domainsDetailToggler.toggleDetail}"
        
image="images/tree-collapse.gif">
                        </h:commandButton>
                        <h:commandButton
        
rendered="#{!domainsDetailToggler.currentDetailExpanded}"
        
action="#{domainsDetailToggler.toggleDetail}"
                                        image="images/tree-expand.gif">
                        </h:commandButton>
        </t:column>

        <t:column width="700px">
                        <f:facet name="header">

                                        <h:outputText
        
value="#{bundle.domain_name}"
        
style="width:30%" />

                        </f:facet>
                        <h:commandLink
                                        immediate="true"
                                        action="go_domainForm"
                                        rendered="true"
                                        value="#{domain.name}">
                                        <t:updateActionListener
        
property="#{domainForm.domainId}"
        
value="#{domain.domainId}" />
                        </h:commandLink>
        </t:column>

        <t:column width="120px">
                        <f:facet name="header">
                                        <h:outputText
value="#{bundle.lists_action}" />
                        </f:facet>

                        <h:panelGrid columns="5">

                                        <h:commandButton
                                                        immediate="true"
        
action="#{domainForm.moveUp}"
                                                        rendered="true"
        
value="#{bundle.lists_action_edit}"
        
title="#{bundle.lists_action_edit}"
        
image="images/icons/arrow-up.gif">
        
<t:updateActionListener
        
property="#{domainForm.domainId}"
        
value="#{domain.domainId}" />
                                        </h:commandButton>

                                        Some other buttons here...

                        </h:panelGrid>
        </t:column>

        <f:facet name="detailStamp">

                Here comes a t:dataTable really similar to the main Data table.
                        
        </f:facet>

        <f:facet name="footer">

        </f:facet>

</t:dataTable>




Thanks in advance for any hint,
