getTree() {

     return $find('navTree')

}

and now I'm trying to access the tree from then parent object like that:

tree = document.getElementById(

"iFrameTreeview").contentWindow.getTree()

var nodes = tree.get_Nodes();

But the broser reports: tree.get_Nodes is not a function

What should I do to get Access to the tree from the parent-site?

Thanks for your support.

getTree() {

     var tree = $find('navTree')

     var nodes = tree.get_allNodes()

     return nodes[0].get_treeView()

}


In the parent frame you've to replace
    var tree = $find('navTree')
with 
    iframeTreeView.getTree()

where iframeTreeView is the name of the iframe, where the tree is located.
