Expand all on tree when dataprovider is an object.

When I first start the application I would like to have the
tree and all nodes fully expanded. My RemoteService returns an
object that looks like the snippet below.
I have seen a lot of code on how to expand all nodes of a
tree, but I do not have a tree.selectedItem yet as I have just
created the app. I would like to add an expand all to the
creationComplete on the tree but I an not sure what to pass the
tree.expandItem. I have tried to pass tree.firstVisibleItem. I have
tried to iterate over the children of the root object of my
dataprovider. I can do it with xml but can't seem to figure it out
using an object. Any ideas?

I tested with your data structure and the following worked
for me. I called expandAll(myTree,true) on creationComplete and all
nodes were open on load.

  • JTree - How to Expand all Nodes in the Tree

    I have a tree that has one primary node, two sub-nodes, and multiple sub-sub-nodes under those. I want to expand (show) all these nodes in the tree when the tree first loads. I tried expandRow() but that only seems to expand one row at a time by entering a single integer for the row. Is there any way to expand all rows/nodes when loading the tree?

  • Why when I create a object in system automaticlly store in $TMP?

    Hi, all
    As title, when I create a object in my quality system , always automatically store the object in the $TMP,
    I have to modify it from menu Goto->Object Directory Entry-> Change Package.
    I hope when I crate a object automatically store in the package NOT $TMP.
    Edited by: xuehui li on Jul 9, 2010 4:50 AM

    Hi,  But when I create a new DTP NO asking me let me create or select a place to store.  Just automatically store in $TMP immediately!
    So I have to go to menu 'Goto-> Object Directory Entry->' modify the package from $TMP to my working package.
    so it is very strange!  I think for sure there is somewhere to set up this option to DONOT store at $TMP automatically instead of asking for me store in where.

  • Tree table-initially expand all nodes raises error when closing a node 11g

    Hello,
    Frank Nimphius posted a blog entry about how to initially display all the nodes in a tree or table here:

    This works very well. However, when the user tries to close a node, a NullPointerException is thrown.
    Below is the stacktrace.
    Does anyone know how to work around that issue?

    OK I have tried Frank's suggestion about the 2 entries in the managed bean and it works but I cannot collapse my child node !
    I have a Master-Detail-Detail setup.
    In the Grandparent I have this :
    RowKeySet rks = new RowKeySet(true);
    table1.setDisclosureState(rks);
    this.grandParentTable = table1;
    and in my Parent table I have this :
    RowKeySet rks = new RowKeySet(true);
    table2.setDisclosureState(rks);
    this.parentTable = table2;
    ie the same.
    In my child I have nothing just the default accessors.
    The collapse works OK for the Grandparent but when I click Hide for the Parent it does not do anything - no error message either.
    cheers

  • How to disable "Expand All" and "Collapse All" when no node in a tree

    I have a <af:tree> inside <af:panelCollection>.
    All items under viewMenu like "Expand", "Expand All Below", "Collapse All Below", "Expand All" , "Collapse All", "Scroll to First" and "Scroll to Last" are implemented by default.
    When there is no node in a tree, "Expand", "Expand All Below", and "Collapse All Below" are grey out.
    However, "Expand All" , "Collapse All", "Scroll to First" and "Scroll to Last" are still enabled to be clicked.
    Is there any way we can diable them when no node?

    When I highlight last node in the tree and all nodes are collapsed, I see "Expand All Below" enabled but "Collapse All Below" disabled. Which is expected. Expand All Below will expand all the child nodes under a node.
    QA filed a bug said that "Expand All Below" should be disabled since no node below it. However, I don't find any place to control them. Can you confirm this? Or you know some way to do this?It it not a bug then. You don't have to control it and framework takes care of enabling and disabling it accordingly.
    If you need to expand all the nodes programatically, check this out.

  • 'Expand All' icon in a tree structure?

    Hi experts,
    If we create a tree UI element in ABAP WD, we automatically get a 'Collapse All' icon.Is it possible to have a 'Expand All' icon as well?
    thanks in advance,
    Pras

    Hello Pras,
    You will not get any Collapse All icon when you create a tree UI Element .
    You can expand or collapse the tree by clicking on the  Parent Elements in the tree.
    If you want to explicitly handle the Expand All and Collapse All functionality you need to put a button in the toolbar with name Expand ALL and handle it explicitly by setting attribute EXPANDED to abap_true for each and every element in the tree for Expand All action and vice versa for Collapse All.
    Hope this is of some help.
    Regards,
    Ismail.

  • Htmlb:tree: Expand All

    I tried to implement an "Expand All" functionality for my htmlb:tree. Strangely, I can change the nodes in the tree table, but they are still displayed as closed on the screen.
    LOOP AT me->t_tree ASSIGNING <fs> WHERE status = cl_htmlb_treenode=>c_treenode_closed
                                             OR toggle = cl_bdv_co=>c_true.
          <fs>-status = cl_htmlb_treenode=>c_treenode_open.
          <fs>-toggle = cl_bdv_co=>c_false.
    ENDLOOP.
    Why is this? Has this anything to do with the TOGGLE functionality of the tree (which loads certain subtrees with a new server event) ?

    >Has anybody an explanation for this
    Delta-Handling is half Black Magic Voodoo anyway.  I assume that the DH server side cache doesn't see any change in those fields (since you have removed them) and therefore doesn't resend them to the client (it only sends changed values).
    The Client side cache still has the old values in memory and didn't get an update from the server.  Therefore it still renders the old values.
    You might try placing a delta handler block around your tree coding:
    <bsp:deltaHandlerBlock id="protectionR2" >
        <htmlb:tree ... />
    </bsp:deltaHandlerBlock>
    You can try playing with the attributes of the DHBlock.  Try attribute clientCacheClear when you want force a change to the tree.

  • How to remove Expand All in view menu of tree table

    Hi,
    I want to remove Expand All in view menu of tree table. How to do that?
    Regards,
    Raghu.

    I am having the exact same problem.
    However, I believe that displaying large amount of data via a tree table is fine as the user is able to quickly drill in to the data of interest.
    It is just that the 'Expand All' option (as implemented) does not make sense in my case.
    Given that I cannot hide it, is there an easy way to change it's behavior so that it does nothing (or provide an 'No implemented' alert).
    I don't have the time/experience to implement custom menu items.
    Thanks

  • Tree error, after Expand All, then collapsing any node, ORA-6502/6512

    Has anyone seen this problem with the Tree?
    Normal Tree mode works great, can expand and collapse nodes with no problem.
    I can Expand All, Collapse All, and Reset Tree without problems.
    However, if I select Expand All, and then try to collapse any node, I get this error.
    Unexpected error ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at line 1
    My database is 9.2.0.4, and there are 1,138 records in my tree table, with id NUMBER(8), pid NUMBER(8), and name VARCHAR2(100).
    my tree query is:

    "PID" pid,

    My root tree query is:select "ID" id, "PID" pid, "NAME" name, null link, null a1, null a2 from "#OWNER#"."PARAM_TREE" where id=0

    Hi all,

    I am also using DIV together with javascript in the tree region so that the selected node is always on top of the page.

  • UIX Tree: "Expand All" Functionality

    Hello,
    I have a question about the Tree in UIX. We are using the Tree component in a UIX Page (JDeveloper 10.1.2). With the tree we also make use of the ClientStateTreeDataProxy class.
    It is possible to expand and collapse the tree, but I want to have 1 button to be able to expand all nodes on the first level of the tree or if this isn't possible to expand all the nodes.
    I have try to simulate this using struts actions, but I'm unable to simulate the state request-parameter. I also try to look if something is possible with the ClientStateTreeDataProxy class. Which possibilities are there to manipulate the tree component?
    Thanks, Dennis

    Thanx Jeanne,
    You brought me on a idea with the UIX Developer's Guide and EXPANDABLE_EXPANDED value.
    I couldn't figure out how the expand property was filled, because it wasn't done in the ADF BC ViewObject. We have a Utility class that creates a DataObject from the ViewObject Data and here the expand property was set.
    Now it was easy to build a ExpandAll option. It is possible to access the HttpServletRequest object were the DataObject is created. By setting a attribute in the request I could react on that and give the expand property indeed the value EXPANDABLE_EXPANDED.

    2 - run Option #4 to rebuild the database.
    Fix #2
    Using iPhoto Library Manager  to Rebuild Your iPhoto Library
    1 - download iPhoto Library Manager and launch.
    2 - click on the Add Library button and select the library you want to add in the selection window..
    3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option.
    4 - In the next  window name the new library and select the location you want it to be placed.

  • Expand all folders in the detailed navigation by default on click of Role

    Hi All,
    I have a requirement on expand all the folders in the detailed navigation by defalut when we click a Role in the Fist level navigation.
    Please have a look about our requirement as mentioned below.
    ->Role1(First Level Navigation)
       ->Wokset1(Second Level)
           -> Folder1(Detailed Navigation entry Folder)
                  -> Folder2

                       Page4
                  -> Folder4
                       Page5
                       Page6
    When the user clicks on Role1 then automatically all the folders in the detailed navigation should be expanded by default then user could see all the pages displayed in all folders. currently the functionality is collapsed all the folders by default in the detailed navigation then user has to expand the folders manually.
    Regading this issue, i had seen couple of threads on the same but getting confusion what is the exact solution for the solution.
    in those existing threads some people has mentioned that need to change code in the lightdetailnavigation.par or some other mentioned that it is not worked out even do the required changes in the code of light detail navigation part file. there is no clarity in the existing threads for getting  the exact solution . please let me know what are the properties needs to be changed at folder level or workset level to make sure all the folders should be expanded by default in the detailed navigation??
    Currently we are using portal 7.0 version.
    Any pointers in this regard would be the great help to us??
    Thanks in advance.

    PortalUser
    Edited by: PortalUser100 on Jan 22, 2011 10:15 AM

    Hi,
    To expand all the folder by default, we need to set the property of the detailed navigation tree.
    Open your framework page in the content administration.
    Check on the detailed navigation check box and click on the properties button.
    In the properties, set the value of initial state= OPEN .
    This will expand all the folders by default.
    Hope you understood.
