Hi Sean, 

  

I am using the tree2 in Myfaces and my requirement is to get the data
from the database and build the tree nodes every time a node is
expanded. If an expanded node is collapsed I want to remove the nodes
under this node from the tree and add the nodes afresh by getting the
data from the database when that node is expanded again.

  

I am facing the problem that even if I remove the child nodes of the
node that I collapse, when I add the nodes again when I expand that
node it seems to remember the state of the child nodes before I
collapsed the parent node and removed these child nodes. So if I had a
child node which was expanded before I removed it, the next time I
expand the parent node and add these child nodes and I click on this
child node that was expanded it will not expand on the first click as
it was expanded when I removed this node. On the second click It
expands. I believe it is collapsing the state on the first click and
on the second click it is then expanding. How do I remove the state of
the child nodes that I remove from the tree.

  

I use….. 

  

List children = node.getChildren(); 

Children.removeAll(children); 

  

…. to remove the nodes. Is there another better way to remove the
nodes or am I doing it correctly. IF this is correct then how do I
remove the states of the nodes the tree maintains.

  

Your help is much appreciated. 

  

Thank you, 

Hitesh
