Hi Arvind,
It can be implemented by the following way.
In JSF -->
<h:form id="Form1" >
<t:tree2 id="folderTree"
value="#{...}"
var="treeItem" varNodeToggler="t"
clientSideToggle="false"
binding="#{Bean.tree}" >
- - - --
- - - --
</t:tree2>
<h:inputHidden value="#{CurrentProgramsCRUD.initialExpandFlag}"/>
</h:form>
And in your backing bean keep the following
private HtmlTree _tree;
boolean initialExpandFlag=true;
public void setTree(HtmlTree tree) {
_tree = tree;
}
public HtmlTree getTree() {
return _tree;
}
public String expandAll() {
_tree.expandAll();
return null;
}
public boolean isInitialExpandFlag() {
if(initialExpandFlag){
_tree=(HtmlTree)FacesContext.getCurrentInstance().getViewRoot().findComponent("
Form1:folderTree");
expandAll();
initialExpandFlag=false;
try {
FacesContext.getCurrentInstance().getExternalContext()
.redirect("home/HomePage.faces"); //change this to appropriate path
} catch (Exception e) {
e.printStackTrace();
}
}
return initialExpandFlag;
}
public void setInitialExpandFlag(boolean initialExpandFlag) {
this.initialExpandFlag = initialExpandFlag;
}
Please let us know if you get any better way to implement this.

Koushik Das
