Answer 1

1) create a item Hierarchical Tree,
ANS: The tree is created
2) put this to pull in data to the Tree
DECLARE
l_query VARCHAR2(500);
BEGIN
l_query := '';
FTREE.SET_TREE_PROPERTY ( c_tree_blk_item_nm, FTREE.QUERY_TEXT, l_query );
FTREE.POPULATE_TREE ( c_tree_blk_item_nm );
go_node ( c_tree_root_node );
IF FTREE.GET_TREE_PROPERTY (c_tree_blk_item_nm, FTREE.NODE_COUNT ) = 1 THEN
po_found := FALSE;
ELSE
po_found := TRUE;
END IF;
END;
Ans: I wrote this code in WHEN_NEW_FORM_INSTANCE trigger. But the code didnot got compiled . I did cut and paste of query too.
Pls help me in defining the c_tree_blk_item_nm and go_node ( c_tree_root_node ). I was thinking some code of this type would work.
The code itself didnot got compiled. It didnot ran.
3) put this coding into WHEN-TREE-NODE-SELECTED trigger under the item, this is to populate the data to other block when u select the tree node.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
GO_BLOCK ( 'BK_AGT' );
EXECUTE_QUERY;
SYNCHRONIZE;
end if;
BK_AGT is the 2nd control block .
Help me in solution for this scenario in creating the hierarchical tree in forms6i.
