ok, this is maybe quick and dirty, but it works for me
I now have a tree checkboxes and able to keep state on serverside
and it actually works very well :)
Not sure how this affects, if youre only interested in single-selection. But i
think this works also:
TreeState.java
public void setSelectedPath(TreePath selection)
{
setExpandedState(selection, true);
this.selectedPath = selection;
if (treeSelectionModel.isPathSelected(selection)) { // Hack
treeSelectionModel.removeSelectionPath(selection);
} else {
treeSelectionModel.addSelectionPath(selection);
}
}
TreeState.java:
protected final TreeState newTreeState(final TreeModel treeModel, final
boolean rootVisible)
{
final TreeState treeState = new TreeState();
final TreeSelectionModel treeSelectionModel = new
DefaultTreeSelectionModel();
treeSelectionModel.setSelectionMode(TreeSelectionModel.DISCONTIGUOUS_TREE_SELECTION);
treeState.setModel(treeModel);
treeState.setSelectionModel(treeSelectionModel);
treeState.setRootVisible(rootVisible);
treeModel.addTreeModelListener(treeState);
return treeState;
}
