Hello all,

I have a little problem with the back button in Seam. We have an overview page, in which you can select an entry to get to a detail page.
Say, we have 2 entries in our overview page. I select the first one, I get redirected tothe detail page. After going back with the browser back button and select the same entry again, all is ok.
If I select another entry, a null value is passed into the method showMember (see below).

Here some code fragments, hoping someone can help me in this issue:

ActionBean defining the DataModel

@Name("SearchAction")
@Scope(ScopeType.SESSION)
public class SearchActionBean implements Serializable {

 ...

    @In(create=true)
    private FacesMessages facesMessages;

    @DataModel
    private List<Invoice> invoices = null;

    public void find() {
        // queryInvoices
    }

 ...

ActionBean for the detail information

@Name("showActionBean")
@Scope(ScopeType.SESSION)
public class ShowActionBean implements Serializable {

...
    @In()
    @Out(required=false)
    private Member member;

  public void showMember(Member member) {
        this.member = member;
    }
 ...

Fagment from the .xhtml

...
<rich:dataTable id="invoiceList"
                columnClasses="col"
                value="#{invoices}"
                var="inv" >
     <rich:column width="55" sortBy="#{inv.documentNumber}">
           <f:facet name="header">
              <h:outputText styleClass="headerText" value="#{messages['documentNo']}" />
           </f:facet>
           #{inv.documentNumber}
     </rich:column>
     <rich:column width="50" sortBy="#{inv.documentDate}">
           <f:facet name="header">
              <h:outputText styleClass="headerText" value="#{messages['documentDate']}" />
           </f:facet>
           <h:outputText value="#{inv.documentDate}"><f:convertDateTime pattern="#{commonDataHelper.datePattern}" type="date" /></h:outputText>
      </rich:column>
                                
      <rich:column width="50" sortBy="#{inv.member.username}">
           <f:facet name="header">#{messages['username']}</f:facet>
           <s:link action="#{showAction.showMember(inv.member)}" styleClass="noDecoration">#{inv.member.username}</s:link>
      </rich:column>
...                            

pages.xml

....
<page view-id="/invoice/invoiceSearch.xhtml">
        
    <navigation from-action="#{showAction.showMember(inv.member)}">
        <redirect view-id="/protected/memberDetail.xhtml"/>
    </navigation>

</page>
...

I tried the @DataModelSection, and get the selected entry direct from the search action instead of the var from the rich:dataTable.

I don't know if this is a problem with Seam and RichFaces !?!

Our environment:

• Seam 2.2.0.GA


• RichFaces 3.2.2.SR1


• Trinidad 1.2.12

Hoping someone could point me on what I'm missing.

Regards
Marco
