Hello,
I have tree with check-boxed leafs and attached adviseNodeOpened method which returns TRUE if node in subtree is checked, otherwise it returns FALSE.
public Boolean adviseNodeExpand(UITree tree)
{
boolean subnodeSelected = isSubnodeSelected(tree.getRowData());
if (subnodeSelected)
{
return Boolean.TRUE;
}
return Boolean.FALSE;
}
The idea is to display tree with expanded checked nodes. This works fine, but there is a problem that this methods is also called on subsequent user clicks which results with expanded node not collapsing and collapsed nodes not expanding.
I need something to distinguish if this advisor is called after the tree is shown to user and return null if this is true.
Thanx for help.
