Tree interface concept for hierarchical data creation/modification

Question

I am designing an interface for hierarchical data creation and maintenance. The interface will have to provide all basic data modifications options:
edit an existing node, add new child/parent/sibling, as well as removing, sorting, dragging and dropping nodes around. Flex tree control is fully capable of all these functions while coding is not going to be a simple task. Has anyone worked on something like this? Any conceptual ideas?
Thanks

WOW Odie! You're awesome !! It worked like a charm, I created a view as you suggested:
CREATE OR REPLACE FORCE VIEW "VIEW_TASKS_PROJECTS_TREE" ("ID", "PARENT_ID", "NODE_NAME") AS
SELECT to_char(id) as id
, null as parent_id
, project_name as node_name
FROM eba_task_projects
UNION ALL
SELECT to_char(id)
, to_char(project_id)
, task_name
FROM eba_task_tasks;
And then I created a new tree with the defaults and customized the Tree query a bit (just added the links really):
select case when connect_by_isleaf = 1 then 0
when level = 1 then 1
else -1
end as status,
level,
"NODE_NAME" as title,
null as icon,
"ID" as value,
null as tooltip,
'f?p=&APP_ID.:22:&SESSION.::NO::P22_ID,P22_PREV_PAGE:' || "ID" || ',3' as link
from "#OWNER#"."VIEW_TASKS_PROJECTS_TREE"
start with "PARENT_ID" is null
connect by prior "ID" = "PARENT_ID"
order siblings by "NODE_NAME"
Thanks man, you saved me a lot of time and headaches :)
