Answer 1

node_value is only item which have transfer the form or report name
Trigger Name : WHEN-TREE-NODE-ACTIVATED
Declare      
     htree                Item ;
Begin
     --clear_values;
--           htree := Find_Item('tree.htree');
-- Find the value of the node clicked on.
:node_value := ftree.Get_Tree_Node_Property(htree, :SYSTEM.trigger_NODE, Ftree.NODE_VALUE);
----Above node value transfer the procedure and call the form with node_value(Form Name)
     Execute_CMD_PROC;
Exception
     When Others Then Null;
End ;
when i enter then no value but when i enter+tab then show the form
