Issue with Tree view

Hello experts,
I am facing a very strange issue with tree view.
I have created a custom component with a tree view. All data are coming in the tree view. But the strange thing is that the data is not getting displayed on the screen.
I am sure about the data because, when I am selecting a line from the tree, the data from that line is coming to the main screen.
Please help!!

Debolina

Hi experts...
Any pointers to this issue???
Please help!

  • Table with tree view on master column

    Hi,
    I'm trying to generate a table with tree view on the master column and I get the table values from an RFC.
    The problem is that I need to control some properties like "expanded" or "isLeaf" and I can't add the value attributes to the model node to control the rows.
    Any ideia on how to overcome this (what i  think is a) problem?
    Thanks for the help.

    Hi Subramanian,
    Maybe I didn't explain myself right. I also followed that tutorial with success but in this case i have on my custom controller:
    -MyNode (model node)
      - Output
        - MyTable
          - attribute 1 (model attribute)
    In my context/view controller the only way i can map that node is by using a model node referecing "MyTable" but this way i can't add any of my attributes to same level of the attributes (is that the ideia right?).
    I also tried to recreate the structure in the view with value nodes and value attributes with the same type as the model attributes and then bind them but i always get "Incompatible context element type".
    Am i missing something?

  • SQL editor with tree view

    We are working on some extraordiary long SQL stored procedure. Due to the shear size and IF/ELSE nesting it is very tedious to understand the logic .
    What I am looking for is an SQL editor with tree view, where we can see IF/ ELSE, LOOP etc block as nodes. For example expand a node and see all blcoks of code within it.
    + IF block 1
    expand---
    -IF blcok 1
    +IF block 1.1
    +IF block 1.2
    further expand
    -IF blcok 1
    +IF block 1.1
    -IF block 1.2
    IF block 1.2.1

    Do some Google searches for a text editor that supports "folding".

  • Issue With Tree

    Hi All,
    We have an strange problem in tree population.
    We are using ftreen.add_tree_data built-in for the population of the next level on when-tree-node-expand trigger.
    On the population of the specific data it is giving the error FRM-47337 Tree node cannot be null
    I had checked the tree query on backend it does not return null.
    But when i do the same functionalty with ftreen.add_tree_node with help of loop means now node add one by one it is working fine.
    I donot have the reason why ftree.add_tree_data giving the error and why it is working fine by ftreen.add_tree_node.
    I hope experts will help me out.

  • File Manager with tree view

    I've been using Cinnamon with the Nemo file manager for a while now but I'm wanting to remove Cinnamon and have only Openbox and Awesome installed. The only thing that's stopping me now is I'm unsure of what to use for a file manager. The feature of Nemo that I really like is the ability to show folders in tree view in the main pane when in detailed list view. I know that most of them probably have the tree feature in a side pane but I want it in the main pane.
    I'd like something with as few dependencies as possible since I'm wanting a more minimal approach to my system. Nemo requires Cinnamon, I'm guessing that Nautilus has the feature that I'm looking for as well but that requires Gnome.
    Can anyone recommend another file manager with this feature? Or is there any way to install Nemo/Nautilus without their desktop dependencies?

    drcouzelis wrote:It doesn't look like Nemo requires Cinnamon. What do you mean?
    claire ~ % pacman -Qi nemo
    Name : nemo
    [snip]
    Depends On : libexif gvfs dconf desktop-file-utils exempi python2
    cinnamon-desktop gnome-icon-theme libnotify libxml2
    cinnamon-translations
    I think this is what is meant.

    Not really, since those libraries are required to run the respective file manager.

  • [Win/CS3] Problem with tree view nodes display In Release Version of InDesign

    b [Win/CS3]
    Hi All,
    I am Facing a problem from last few days.I have a dialog on which i have a treeview ListBox.I am filling this listBox dynamically.On a Button click Event.
    My requirement is to show Some text value on the node and Index value on the back end.So When i select String1 the index1 should be Selected.
    b This Listbox is working fine ON Debug Version. But Crashing On Release Version.That seems Strange to me..........?????????
    b in DialogObserver::Update on button click event
    NodeID node = IDCGridNodeID::Create(IndexX);
    treeMgr->NodeAdded(node);
    b and in TreeviewMgr::ApplyDataToWidget
    TreeNodePtr<IDCGridNodeID> nodeID(node);
    PMString IndexNo= nodeID->GetName();
    I am going to database and retrieving string value according to that
    IndexNo.
    WCHAR Buf[200];// this contains value retrieve from database
    Then i am converting WCHAR[] to CHAR[] BY using
    size_t origsize = wcslen(Buf) + 1 ;
    const size_t newsize = 100;
    size_t convertedChars = 0;
    char nstring[newsize];
    wcstombs_s (&convertedChars, nstring, origsize, buf, _TRUNCATE);
    PMString StringToDisplay(nstring);
    //Till here its working fine
    But when i am setting this value as Node name
    style.Translate();
    setNodeName( widgetList, StringToDisplay, kIDCTVTextWidgetID );
    and function return kTrue; statement executed The application is crashing.
    With error showing
    b INdesign Encountered a problem Needs to close.
    I Am not able to find out why this is not working on Release while it is working fine on debug version..???????????????????
    Is I am missing or Made some changes For release version..????
    Thanks,

    Hi Michael,
    Thanks for your reply.
    The lines
    NodeID node = IDCGridNodeID::Create(IndexX);
    treeMgr->NodeAdded(node);
    are working fine for Both Debug N Release version.The Application Is crashing In tree view manager class as i explained.
    while it works fine without having even a single warning in debug version.
    I read the document and i find out if i want to add node in treeview i have to call
    treeMgr->NodeAdded(node);
    which will call manager
    b and in TreeviewMgr::ApplyDataToWidget
    i am getting my node name as
    TreeNodePtr<IDCGridNodeID> nodeID(node);
    PMString IndexNo= nodeID->GetName();
    I don't think that something is wrong in this but i am not sure becoz i am new in indesign development.
    for adding nodes i referred the SDK examples.I found the same code for adding.

  • Problem with tree view

    Hello and good morning,
    i´ve got a problem with a tree view in one of our web dynpro applications.
    The tree view act´s as a menu. For example:
    the highest element is: personal
    If you open personal you see:
    recruiting
    payment
    and so on...
    Our Problem is...
    You can open the tree element by clicking on the little box left from the tree-element text.But we want that the tree-element is also "line-sensitieve". This means, the next elements should not only appear by clicking the box, also by clicking simply the line.
    Is this possible.

  • File manager with tree view in main pane?

    I'm looking for a file manager with something similar to Nautilus' list view, with a list and tree structure as a main view.
    The nautilus one is awesome, but nautilus has qwerks if you don't use gnome (wants to control desktop, panels are very restricted, etc.)
    Does anyone know of a file manager with a view similar to this that I can try out?

    I've seen a few things on spacefm, and played with it a bit. Took me 3 minutes and 2 segmentation faults to find the setting to change views, and it still doesn't have the ability I want, so still a bit too buggy for me.
    Pcmanfm is a good all around filemanager, but doesn't have that feature either.
    I played with a slew of file managers one day looking for similar things, maybe I should try that again and branch out further than what's in the repos.
    More suggestions?

  • Issue in Tree View Enhancement

    Hello Experts,
    I have a Tree View and its related Context Node Class. Due to some requirement I need to enhance the same.
    I have done the following steps:
    1. Enhance the View which eventually enhanced the CTXT class  to Z_CTXT as well.
    2. I am trying to enhance the Tree View context node( say IBASE in my example).
    When I do the same, it is giving me an error saying that
    Method CTXT - CREATE_IBASE does not exist.
    Just to recheck I went to the parent class of Z_CTXT which is CTXT and found the method was very much there.
    Refer standard component ICCMP_IBASE  View: IBTreeResultList  Context Node: IBASE. My question is related to this context node.
    Thanks in advance.
    Best Regards,
    Vinamra.

    Hi Vinamra,
    When you enhance the view by default CTXT class also will be enhanced, when you enhance the context node then only system will create corresponding method create_"context node name" in your Z_CTXT class.
    Did you check Z_CTXT class for the create_ibase method, This class should have added this method with code like this
    model   = owner->create_model(
         class_name     = 'ZCLICCMP_IB_IBTREERESULTL_CN00' "cl_crm_ic_ibase_constants=>gc_ibtree_firstlevel_class "#EC NOTEXT
          model_id       = cl_crm_ic_ibase_constants=>gc_ibtree_node_name ). "#EC NOTEXT
      ibasetree ?= model.
    Best Regards,
    Dharmakasi.

  • Selection issue in tree view

    Hi.
    I have one strange issue in Z tree view. After selection of one row in tree view, I can next select only the rows the are below the selected row (doesn't matter if they are on lower or upper level). However I can't select the row that is displayed higher of the selected row.
    Anyone has an idea where could be the problem?
    Best regards.

    Tnx for answering. I checked if the entity is read correctly and in on_select event I get data OK. So I pass data to collection at the end.
    here is the code...
    METHOD eh_onselect.

           tnode->selected = abap_true.
           bo = typed_context->itgroup->get_bo( lv_event->row_key )    .

    maybe any suggestion?

  • Issue with Adobe Viewer.

    I am a Coldfusion developer. I have an application that takes some coldfusion variables and populates a pdf form that was created in LiveCycle. In the past this worked fine. Today someone told me of an issue they are having. Now when the view this pdf in a browser the fields are not populated. This is a major drawback from the way things use to work. Is this a bug or did you intend to do this?

    Yes, I have tested on Chrome, Firefox, Safari, Opera and IE. It does not work in Firefox 19 or in Chrome 25. In Firefox I only get the hard coded text of the form. In Chrome I get the placeholder text in the form fields. Firefox shows a yellow message at the top "This PDF document might not be displayed correclty." and their is a button labeled Open With Different Viewer. Some of my users are not very tech savy and may miss that option. I am populating the form using the cfpdfform tag with an action of populate on a pdf form created in live cycle. I use the cfpdfformparam tag to put the values in the fields.

  • Performance Issue with PAY_BALANCE_VALUES_V View in Oracle R12

    Dear all ,
      We have recently upgraded from 11i(11.5.10.2) to R12(12.1.3). We are facing one Issue with slow performance of the queries where PAY_BALANCE_VALUES_V is used. We have so many reports & logic in Payroll which uses this View.
    In 11i this works fine, however in R12 it takes very long time. There are no configuration changes we have done from 11i to R12.
    Is there any way to optimize the performance or alternate way to retrieve the Balances Data in Payroll ?
    Any heads up would be highly Appreciated.
    Thanks,
    Razi

    Hi Razi,
    The balance related performance issue is written in the following note.
    Note:1494344.1 UK Payslip Generation - Self Service Program Takes Much Time To Complete (Performance Issue)
    This issue was fixed in HR_PF.B RUP6 or patch:14376786. Did you apply this patch? If not, I suggest you apply it.
    Also, HR_PF.B RUP6 has some balance related performance issues.
    If you already have applied HR_PF.B RUP6, I suggest you log a SR with SQL trace.
    Thanks,

  • Issue with Smart View when trying to connect to Planning/Essbase

    Hi All,
    I'm facing this issue with Hyperion 11.1.1.3 & 11.1.2. In Excel, I've created a connection in SmartView by giving the URL as http://ServerName:8300/HyperionPlanning/SmartView. After that i'm able to see "Servers" and when i started expanding that, it displayed the server name. When i clicked on the server name, it should display the Planning Application name right ? instead of that just a Cuble symbol is displaying. Do i need to make any settings for proper display of the Planning Application names ? This is perfectly working fine with HFM. I'm able to see HFM application names. Pls. advice

    I was trying for shared conenction this morning and it was not working. Now all of sudden it started working. Even i've checked now, the private connection is also working fine with the URL http://planningserver:8300/HyperionPlanning/SmartView

    Well, the thing I always forget and have pulled much hair out over is to add the essbase server access to the planning group.
    Check on that, and I will loosen the rocks in my head to see what else I can suggest.

  • Issue with Sales Views in MM01

    Hi gurus,
    We need to create a material with only views for Basic Data 1&2, and Sales Org. Data 1, Sales Org. Data 2 and Sales General Plant data.
    The sales organization is created but when trying to assign the material (with existing Basic Data 1&2) to the Sales Organization the system is giving error "sales org. and distrib. channel invalid sales area".
    Any idea what additional settings are necessary to assign the material to the sales org. ?
    Thanks!
    VL

    Sales organisation itself is not enough, you have to define distribution channel also:
    SPRO > Enterprise Structure > Definition > Sales and Distribution > Define, copy, delete, check distribution channel
    Distribution channel has to be assigned to sales organisation:
    SPRO > Enterprise Structure > Assignment > Sales and Distribution > Assign distribution channel to sales organization
    Division should also be defined and assigned:
    SPRO > Enterprise Structure > Assignment > Sales and Distribution > Assign division to sales organization
    It's starnge that you want to create material master and still your config has such serious deficiencies...
