UI shell task list: Showing a tree hierarchy in Regional Area

Question

Hi,
We have a requirement where we want a tree to be displayed in the menu model as task list links and clicking on any node in the tree should open up a task flow in the local area.
Given below is one example, in the task list in the UI shell (Regional Area) and the tree should also appear as a link and on clicking any of the nodes should call a task flow with the context getting passed.
A
B
C
Please let me know if you have any idea on how to achieve this functionality.
Thanks,
Rakesh

Hi,
I can't to this time share the whole document or sample. However, the way to do this is quite simple. The document I pointed you to actually contains the soluion (though not in code)
1. Create a managed bean with method for lauching each of the task flows you want to launch (e.g. openCreateDepartmentBTF, openUpdateEmployeesBtf).
2. The managed bean method then uses the the TabContext as shown in the example below
//clicking the link in the customer tree or using the context menu
    //opens the selected customer orders task flow in a new tab in the
    //UI Shell template
    public void openCustomerOrdersTab(ActionEvent actionEvent){       
      //the tree node for customers is a command link
      UIComponent link = (UIComponent) actionEvent.getSource();
      //the command link as custom attributes defined to pass arguments
      //to the task flow. The customerName attribute is a display string
      //to show as the tab title
      String customerName = (String) link.getAttributes().get("customerName");
      //the task flow requires the customer ID as a query parameter
      Object initialQueryArgument = link.getAttributes().get("initialQueryArgument");
      //arguments must be passed in a HashMap to teh task flow to be generic. The UI Shell tab
      //context class is passed implicit
      HashMap taskFlowParameters = new HashMap();
      taskFlowParameters.put("initialQueryArgument", initialQueryArgument);
      taskFlowName = "/WEB-INF/customerOrdersCRUD/customerOrdersCRUD-btf.xml#customerOrdersCRUD-btf";
      //call a private method that accesses the TabContext class to open a new tab
      this._launchActivity(customerName+" Orders", taskFlowName, taskFlowParameters, true);
      this.showInnerToolbar();
    }3) Create the tree similar to
<af:tree value="#{bindings.AllCountries.treeModel}" var="node"
     selectionListener="#{bindings.AllCountries.treeModel.makeCurrent}"
      rowSelection="single" id="t1" autoHeightRows="35">
      <f:facet name="nodeStamp">
              <af:commandLink id="cl4" text="#{node}"
                                           rendered="#{node.hierTypeBinding.viewDefName == 'oracle.summit.model.views.CustomerVO'}"
                                           actionListener="#{tabShellLauncher.openCustomerOrdersTab}"
                                           clientComponent="true">
                                          <f:attribute name="initialQueryArgument"
                                                                         value="#{node.id}"/>
                                          <f:attribute name="customerName"
                                                             value="#{node.name}"/>
                    </af:commandLink>
         </f:facet>
</af:tree>                                                    If you need different command links for different nodes in teh hierarchy, you can add them all and then set its rendered property to
rendered="#{node.hierTypeBinding.viewDefName == 'oracle.summit.model.views.CountryVO'}"
In the above sample, the command link only renders if the VO is CountryVO in the specified package
