How to create dynamic tree component

I am using netbeans 5.5 and visual web pack to develop my jsf application.
I want to add a tree component that will be tied to a table with following columns:
id,parent_id,name
Actually the table stores data in tree structure with parent_id storing the parent of the row.
So a row with parent_id = 0 will be the root nodes of the tree.
When ever any root node is selected i want to fetch its children from the database and populate then as children of that parent node.
The tree can go to any depth so i want to make my tree component dynamic enough to handle this requirement.
How can i accomplish this.
I just want to add listerner for the plus sign of every node so that when the plus sign of that node is clicked i just want to get the id of the corresponding node.

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?

We have 3 regions over 50 plants and probably around 500 corporations.

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .

Well think of it I believe the scenario is too bird viewed hence the solution can't be exact.
But thinking of a possible solution every time a child operation fails have a catch block where you you go back to system if the parent needs to be deleted if yes, call Delete Method on the parent.
Note: Make sure that the decision on whether or not the parent record needs to be deleted will depends on the question "Does Parent Record already has several other children associated to it or not"
Hope this clarifies.

How to create Hierarchy Tree Node structure?

Hi experts,
          I want to know how to create a tree with kind of below Structure:
Root A
         NodeA1
              ITEMA1_IT1
              ITEMA1_IT2
              ITEMA1_IT3
         NodeA2
              ITEMA2_IT1
              ITEMA2_IT2
         NodeA3
              ITEMA3_IT1
              ITEMA3_IT2
              ITEMA3_IT3
              ITEMA3_IT4
So when i click on Root A it shows me, NODEA1, NODEA2 & NODEA3....
when further i click on NODEA1, it shows me items like ITEMA1_IT1,ITEMA1_IT2, ITEMA1_IT3.
when further i click on NODEA2, it shows me items like ITEMA2_IT1,ITEMA2_IT2.
SO item will get loaded when i click on perticular node.
how its possible.
I have gone through SDN so many threads, bt i didn't get exactly for webdynpro ABAP.
Please guide me for the same.
Thanks ,
Saurin Shah

Hi,
you can create the tree you wanted as follows:
1) create a node under your context say "root_node" with cardinality 1..1
2) now create an attribute under it called "text" with type string.
3) now create three nodes under this "root_node" called nodeA1 nodeA2 and nodeA3 with cardinality 0..n
4) now under nodeA1 , nodeA2 and nodeA3 create an attribute called "text" with type string...so each node will have one attribute called "text" of type string...
5) now create a node under nodeA1 called "itemA1" with cardinlity 0..n
6) now create an attribute called "text" of type string under this node "itemA"...
7) repeat step 5 and 6 for the other two nodes...nodeA2 and nodeA3
8) now create six supply functionsthese functions will supply the text values for your nodes-
I created like this:
FILL_ITEM1
FILL_ITEM2
FILL_ITEM3
FILL_NODEA1
FILL_NODEA2
FILL_NODEA3
Note:*******************my view is called MAIN******************
hence the coding is
data
    lt_elements type if_main=>elements_nodea1.
if you view is called view1...than the data declaration would be
data
    lt_elements type if_view1=>elements_nodea1.
9) go to each node and assign the supply function respectively....you can assign this by going to context tab and selecting the node you want to assign the supply function to and just type in the name of the supply funciton or do the help for that field by clicking on the little square btn...
10) now we go the layout tab and put the tree ui on the layout....bind the datasource property to the context node "root_node"
and bind the rootText property to the attribute "text" of the root_node...
11) now right click on this tree ui element under the ROOTUIELEMENTCONTAINER and select "insert node type" ...a box will appear where you can see it has two types of node for you....one is tree_node_type and other one is tree_item_type...
create three nodes with tree_node_type with names "nodeA1" nodeA2 and nodeA3 and three with tree_item_type with names "itemA1" itemA2 and itemA3...
12) now bind all these node types and item types data sources and texts with corresponding nodes and attributes under your context...
so nodeA1datasource will get bind to context nodeA1 and itemA1 data source will get bind to itemA1 from context..and so on...
13) now in the wddoinit method: I setup the text for the root node.....
DATA lo_nd_root_node TYPE REF TO if_wd_context_node.
DATA lo_el_root_node TYPE REF TO if_wd_context_element.
DATA ls_root_node TYPE wd_this->element_root_node.
DATA lv_root_txt TYPE wd_this->element_root_node-root_txt.
navigate from <CONTEXT> to <ROOT_NODE> via lead selection
lo_nd_root_node = wd_context->get_child_node( name = wd_this->wdctx_root_node ).
get element via lead selection
lo_el_root_node = lo_nd_root_node->get_element( ).
@TODO fill attribute
lv_root_txt = 'Root Node'.
set single attribute
lo_el_root_node->set_attribute(
    name = `ROOT_TXT`
    value = lv_root_txt ).
hope this will give you the solution you are looking for...
Thanks...

how to create a tree in tree?

Hello Luo Cheng
Did you mean to have multiple tree control within a tree control?
I am not understanding what business purpose will this serve to have a tree control inside other? You can always have a specific node and when expanded list all the related nodes.
To have a tree control inside another tree control is not possible.
