rich:tree lazy loading of the childs

[tushe]

Hello every body.
I have a huge amount of hierarchical data 15000 and more . I have to present them in a tree.
The point here is that I have to load only the requested childs one level at a time not recursively to the bottom.
Do you have any idea how to do that?
Thank you in advance!

Maybe by programmatically creating/updating the tree in a java class?

Hello everybody,
I am developing a lazy loading rich:tree.

<rich:tree id="tree" style="width:300px"
switchType="ajax" ajaxSubmitSelection="true"
value="#{treeStructure.rootNode}" var="dir"                                      nodeSelectListener="#{treeStructure.selectNode}"
componentState="#{treeStructure.treeState}"
adviseNodeOpened="#{treeStructure.openNode}"
ajaxRendered="true" >

<rich:treeNode ajaxRendered="true" id="treeNodeId" changeExpandListener="#{treeStructure.processExpansion}">
......
....

I have readed carefully the post here http://random-thoughts-vortex.blogspot.com/2009/05/richfaces-tree-dynamic-update-of-tree.html .
i have implemented it but still the tree can not render the kids when I click on them.
I've tried many different combinations with different tags and properties but still unsuccessful.
I debugged  it and all of the methods are called properly during runtime as well as the children are loaded lazily and added correctly to the Tree....
Does someone has an idea.
Thanks in advance.
