Yahoo astra tree (how to get nodeLevel)

Hello,
I'm trying to use yahoo astra tree component ( http://developer.yahoo.com/flash/astra-flash/tree/examples.html) , for abaut 2 weeks, but I've a huge problem, I cant manage a way of get the path frmo root to ne child level of the tree.
I need something like
node1
node2
     subnode1
     subnode2
          subsubnode1
node3
node4
when subsubnode1 is clicked, I need to have traced his path, node2.subnode2.subsubnode1
How to get this result?
Thanks
Pluda

hello,
it seems no one uses these astra components.
well, I think the issue is in this piece of code, I can't transverse the tree data, but I think this is the best way to get this working
if(node.nodeLevel == 0) {
            global.v.pai = node.label;
        } else {
            trace(node.nodeLevel);
            var parentPointer:TNode = node.parentNode;
            if(parentPointer is BranchNode) {
                global.v.familia = node.parentNode.label;
            } else {
                while (!(parentPointer is RootNode)) {
                    parentPointer = parentPointer.parentNode;
thanks

    You could look thru the properties/styles of the component to see if there is something that can be set/changed for the background.  An alternative could be to try editing the compoent in the library.

  • TREE, how to get the ITEM of a cl_column_tree?

    Hi guys!
    I built my column tree with 2 columns so far for equipments.
    the equipment id  has 18 char, the node-node_key only 12.  So i decided to put the equipmentid in an item_text.
    My question now is,
    How can i access these items in the method HANDLE_EXPAND_NO_CHILDREN....the events gives me the node_key, but how can i get to the item?
    thanks

    Thanks a lot for all your answers! :)
    I finally got to do something with my little knowledge =P
    I created a new class containing all the data needed for the dataTable (including a "String id").
    And that's what I get:
    <h:column>
         <a:commandLink
              value="#{familyAction.familyDocsByPrj.name}"
              action="#{homeAction.search(familyAction.familydocsByPrj.id)}"

  • .Mac Mail, Yahoo & Leopard Mail - How to get all in sync?

    Hi there,
    I'm trying to get .mac mail to syncronize my yahoo mail and all the folders to my computer and .mac. However, it appears that .mac webmail is not pulling in what is on Yahoo or my computer. Does anyone know what the settings are?
    Thanks!

    >>I have Admin credentials[ Username and Password] , by using this i need to Access all user's mail boxes and Contacts.
    Admin credentials mean nothing in regards to Mailbox access, so to use delegate access you would need to grant rights to the every Mailbox using Add-MailboxPermission (or if you only want access to the Contacts folder use add-mailboxfolderpermission
    to add/change rights on the contacts folder) or you need to setup and use EWS Impersonation
    http://msdn.microsoft.com/en-us/library/office/dd633680(v=exchg.80).aspx .
    >>And i  read aboutimpersonation that all needs permissions.
    By default the only user that can access mailbox content is the owner of the mailbox, you will only be able to access content in a Mailbox if its has been shared with you or you grant youself rights to the mailbox using Exchange Admistrative credentials.
    All of this will leave an audit trail.

  • Using tree - how to get upper levels

    I create a heirarchical tree based on a couple of tables via a record group i create on the fly.
    I then let the user attach documents to the tree nodes. The problem comes that the node may not exist in the database yet as they can build them as they go. So i need to insert all record on tree into table when they attach a document. I dont want to do this before as i am only interested when they are attaching documents - rather than storing all data that may never be used.
    My problem is when they attach the document i want to find all levels in that particular tree to insert them.
    i.e. if my tree is as follows
    1
    -1b
    2
    -2b
    3
    -3b
    -3c
    and the user attaches against 3c I want to insert 3 into the table, then 3b, then the document against 3b, so i need to find out what its uplevel is in this case 3.
    How is best way to do this? i have NODE_DEPTH property - to know its not top level and NODE VALUE to know the value, and NODE_LABEL to know the description but how can i find my uplevel when its not stored in a table anywhere.

    Cant believe i never found that when searching forms help.
    Thanks

  • Yahoo Messenger Screen - How to get rid??

    With my Blackberry Pearl 8100, when I connect to the Internet I get a yahoo Messenger Installation screen EVERYTIME, wanting me to install some software/update! It's not a massive problem as I can just hit the menu button, and select "Go to..." and put my webaddress in there, but it woudl be much neater if I coudl stop getting this Yahoo screen, and go direct to my selected homepage.
    Any ideas?
    I've tried installing the Yahoo messanger, which was successful (I think, not that I use it!) but I still get the yahoo screen each time I connect to the Internet.

    if you are not using Yahoo Messenger, go to Option > advance options > applications and remove those Yahoo related applications. Also go to options> advance options> service books and delete those yahoo related SB.

    dear, there.
    how to change the default search engine? I accidentaly change it from google to yahoo, and I can't get it back. I changed my homepage to google too, but it isn't solved. Thanks

    Clarification:
    I believe now you potentially lose all extensions, plug-ins when you use the new reset function, but you will let me know.
    If that is the case, your find corrupt file method maybe better. However, I reviewed the two help articles and there appear to be more files than just the delete search.json file and a possible search.sqlite file in the Firefox Profile Folder. I am confused. Then I have to find the folders. I think help articles mentioned how to find the profile containing the files, but not sure.

  • How to get the data like a tree in t-code /nEC01 ?

    Dear Friends,
    When using t-code EC01, you can click 'Structure' button, and then click 'Navigation'  button, finally the "SAP organizational objects" will be displayed as a tree - when you double click one item, it will be expaned.
    My problem is, is there any table or view to store these tree data? if not, how could I get them?
    Thanks a lot!
