hi all,
i have a hierarchical tree on my form.
for example i want when user cliced on a node of tree show window.
i used WHEN_TREE_NODE_SELECTED::

/*this codes is a example*/
 if :system.trigger_node=1 then
    show_win('win1');
 elsif :system.trigger_node=2 then
     show_win('win2');
 elsif :system.trigger_node=3 then
     show_win('win3');
 end if;

but problem:
when i click on each node first time this is correct but for example i click on node 1 win 1 shown and then click on node 2(or 3)first showed win1 and second showed win2(or win3).
why?

Please read the Forms Help topic for the ':SYSTEM.TRIGGER_NODE' system variable. This variable returns a value of TYPE NODE not of TYPE number. You should be calling the FTREE.Get_Tree_Node_Property() to get the value of the select tree node. There is a nice example of using this built-in in the help topic for the system variable.
