how can i render the tree in expanded form very first time?

[priyanka.thkr03]

hi,

I am new to rich faces and facing a problem while rendering a tree.

I have a treeNode of rich faces TreeNode. This tree has some children and children can have further children.

I have  a bean for the xhtml page.

In the xhtml page i 'm trying to display the complete expanded tree using :

<rich:tree switchType="client" adviseNodeOpened="#{CMBrowserBean.adviseNodeOpened}" value="#{CMBrowserBean.rootMONode"} var="node">

  <rich:treeNode>

  <h:outputText value="#{node}" />

  </rich:treeNode>

  </rich:tree>
