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. Any help is much appreciated. |
