My tree is coming collapsed when i run my application, i have tried using functions like expandRow(int), setExpandedState(Treepath, boolean), but it doesn't work. Also if i use setExpandedState(Treepath, boolean) function, then in collapsed state Treepath argument will be null, so there is no point in using it. please help me!! thanks in advance.
