Before populating the tree, you should populate the group:
DECLARE
rg_tables RECORDGROUP;
BEGIN
rg_tables := Find_Group('RG_TABLES');
IF Populate_Group(rg_tables) = 0 THEN
ftree.populate_tree('TAB_HIERARCHY.TAB_TREE');
END IF;
END;
I have no problems with expanding nodes, but we use Forms [32 Bit]
Version 6.0.8.12.1 (Production).
