ViewObject row is always zero

Hello

I want to get ViewObject Programatically to do AppModuleImp.java and use the following code

Notice of ViewObjectImpl = getVO_Pro1();
int count = view.getRowCount ();
System.out.println ("count:" + count);
for (int i = 0; i < count; i ++) {}

Line r = view.getRowAtRangeIndex (i);
If (r! = null) {}
If (r.getAttribute ("ProgramName")! = null) {}
System.out.println (r.getAttribute("ProgramName"));
{ } else{}
System.out.println ("attribute is null");
}
} else {}
System.out.println ("Row:" + i + "is null");
}

but every time the row is null. make a body to know what is happening? If I run appmodule all right.

User, please tell us your Jdev version!

When you try to run the code you posted?

This is a hostel of the method of the module of the application?

Did you use the debugger to check the code?

The County says print? How many lines is available?

The code you use I had no best practices. GetRowCount() reads all lines in memory which can lead to errors of memory. Instead, you must use getEstimatedRowCount() to find out how many lines you got. Then use you the vo is first, next, previous and last method to iterate with breast offer the tire.

  • OAF: row.length always returns 1

    Hello world


    EmployeeVOImpl vo1 = getEmployeeRowVO1 ();
    Line [] row = vo1.getAllRowsInRange ();
    for (int i = 0; i < row.length; i ++) {}
    EmployeeRowVOImpl row2i = row2 (EmployeeVORowImpl);
    .
    .
    .

    }
    The problem is row.length always returns 1 if the loop runs only once.
    If I put vo1.getRowCount () instead of row.length, the loop is one iteration for the second time but in error to EmployeeRowVOImpl row2i = (EmployeeVORowImpl) [i] row2; (oracle.apps.fnd.framework.OAException: java.lang.ArrayIndexOutOfBoundsException: 1).
    System.out.println ("Row count:" + vo1.getRowCount ()); Returns 450
    VO has 450 records.
    What can be wrong here?
    Any suggestions would be really grateful...

    Thank you.

    You can try the code below

    OAViewObject vo = (OAViewObject)getEmployeeRowVO1();
    EmployeeRowVORowImpl row = null;

  • ViewObject get attribute always returns null

    Hi guys,.

    I need your help, I'm going crazy.

    I'm just trying to browse a ViewObject as I did a thousand times but despite getEstimatedRowCount return 1 and the Row inside the SENTENCE object is not null, getattribute always returns null, does not care if I call getAttribute (String) or getAttribut (int)

    This is the last code I tested:

    AppMod = (PeopleFinderAppModuleImpl) this.getApplicationModule () PeopleFinderAppModuleImpl;

    PfUserGetInfoImpl pf_Info = (PfUserGetInfoImpl) appMod.getPfUserGetInfo1 ();

    pf_Info.setp_userid (UserID);

    pf_Info.executeQuery ();

    System.out.println ("# view getEstimatedRowCount:" + pf_Info.getEstimatedRowCount ());

    PfUserGetInfoRowImpl r = null;

    RowSetIterator rsIterator = pf_Info.createRowSetIterator (null);

    While (rsIterator.hasNext ()) {}

    r = (PfUserGetInfoRowImpl) rsIterator.next ();

    System.out.println ("# AttributeCount:" + r.getAttributeCount ());

    String [] uploading = r.getAttributeNames ();

    for (int i = 0; i < attrs.length; i ++) {}

    System.out.println (I + "" + uploading [i] + "=" + r.getAttributeValues () [i]);

    }

    }

    rsIterator.closeRowSetIterator ();

    The output is:

    # userid: EPETRANG

    # Discovers getEstimatedRowCount: 1

    # AttributeCount: 13

    0 Userid = null

    1 name = null

    2 Givenname = null

    3 family name = null

    4 title = null

    5 Dn = null

    6 mail = null

    7 company = null

    8 Department = null

    9 Telephonenumber = null

    Mobile 10 = null

    11 Ipphone = null

    Manager of 12 = null

    My Env record:

    Build JDEVADF_11.1.1.7.0_GENERIC_130226.1400.6493

    1.6.0_45 64-bit JVM

    Of course, the query returns 1 row SQLDeveloper and ApplicationModule compressiometre is as well.

    You see something wrong in the code? I tried to delete and re-create the ViewObject without a bit of luck.

    Hi guys,.

    Thanks to you all.

    This morning I just tried to delete and recreate the Weblogic JDev field and now everything works fine. Looks like that integrated weblogic has been screwed

  • Account not always zero?

    Hello

    Report generation sequence file, as reportgen_txt.seq comes with TestStand, a step called "add an account no. In my understanding, this is the model, as sequential model.seq, but I always saw him again.

    I was interpreting this parameter in the report would say a test had altogether, how many steps because my tests may take a different number of steps. Is my assumption correct that this setting would say total number of steps performed, including all the step is executed for example in a while loop?

    BR

    Petri

    Hi Petri,

    Your understanding is good. ' Add an account of not ' AddReportHeader sequence step adds the total number of steps performed in test runs.

    This parameter in the report will be 0 if you have disabled 'Understand the results of Step' in the dialog box for the corresponding report plugin Report Options.

    I hope this helps.

    Kind regards

  • BUG: VlanID always zero for vSwitch exchanges

    After the upgrade of vCO 5.5 to 5.5.1 I discovered to my dismay that it is now impossible to recover the ID vlan for a traditional portgroup; now, the reported vlanId is always '0' (not null or undefined).

    This is clearly a bug, and in my case, it breaks all sorts of things.

    I use the following code, which worked in 5.5:

    var host = Server.findAllForType ("VC:HostSystem");

    host = host [0] var;

    allpg = Host.config.Network.PortGroup

    for (var n = 0; n < allpg.length; n ++) {}

    Spec = .spec allpg [n];

    var pgvlan = spec.vlanId

    pgname = spec. Name

    System.log ("Portgroup" + pgname + "a vlan" + pgvlan)

    }


    Since version 5.5.1 the vlan ID returned is always 0.

    It is a problem with the service of the inventory. You can tell vCO to NOT use the service of inventory by adding the following line to vmo.properties, then by restarting your vco-Server service:

    com.vmware.o11n.vim.useInventoryService=false
    

    VMware is aware of the issue and will fix it in a future release. In the meantime, you can use the parameter vmo.properties as a work-around

  • Casting of string as int makes it always zero?

    Hello

    I had to do

    _myID = event.selectedRow.getData ("my_id");

    in

    _myID = event.selectedRow.getData("my_id") as int;

    so that it stops, causing a warning when my boyfriend it loads in FlashDevelop (I work in Pro)

    Since then, each myID became 0. for example if event.selectedRow.getData ("request_id") contains "29" becomes 29 at zero.

    What should I do for that "29" becomes 29?

    Thanks for taking a peek.

    var s:String = '29 ';

    int (s) will work and number (s) will strive to convert '29' 29.

  • Limits of a part of the text

    I'm trying to get the limits of a portion of a textFlow. I tried to extract the part via:

    var tf:TextFlow = _textFlow.deepCopy (start, end) as TextFlow;
    trace (TF.flowComposer.numLines);

    I wanted to use the TextLine.getBounds () method to get the bounding box of the text. The number of rows is always zero, so I can't extract the line via

    _textFlow.flowComposer.findLineAtPosition (0).

    I tried to work with compose() and so on, but the number of rows is zero.

    Is there another possibility to get the limits?

    Thanks in advance.

    The number of rows is zero until the text was composed. He must have a controller before being committed.

    If the text is already composed as you like in the original TextFlow, you could get the lines intersecting the area that you care. You can do in the flowComposer handing. That gives the TextFlowLine and you can iterate towards the front on the last lines in the region you care. Here is an example of what this might look like:

    var lineIndex:int = textFlow.flowComposer.findLineIndexAtPosition (startPosition);

    var endLineIndex:int = textFlow.flowComposer.findLineIndexAtPosition (endPosition);

    While (lineIndex<=>

    {

    the var line: TextFlowLine = textFlow.flowComposer.getLineAt (lineIndex);

    ... do something with line...

    ++ lineIndex.

    }

    Hope this helps,

  • Socket RAW InputStream.availalble () in stream wireless network always 0?

    For all BlackBerry networking expert out there.

    The explanation of the problem will be quite long, so I'll try to structure the message to facilitate navigation.

    Introduction

    Recently, we went from HttpConnection to raw sockets in our application.  It wasn't an easy decision (a lot of extra code had to be written and debugged) - it stemmed from the fact that on different devices HttpConnection behaves very differently and sometimes we would just hang out here for always trying to read something, although enough bytes was available in the buffers of the system (I have seen it with my own eyes; can develop if anyone is interested).  There are other reasons, but this has been the main.

    Previously working solution

    Once we went to the outlets and implemented our own HttpConnection (not me - someone to increase their knowledge in networks of BB did this), our problems have disappeared. In order to reduce the chance of getting stuck forever, we check InputStream.available () of the socket and, if there is always a thread. Sleep() 0, for some small interval (makes me cringe, but well, the user makes a call blocking!) then read just one byte (hoping that there might be something).  It worked for all trackball/touchcpad devices and all kinds of connections (SDM is a separate issue, but we managed)...

    New problem

    ... until we have tested the Storm (5.0 Storm1 and Storm2 - both 5.0 behaved similarly) with all, but connections WiFi disabled.  We have connected WiFi router to the company (I then repeated the test at home with my wireless router and got the same results).  BB browser worked fine.  However, our code began fails on our internal waiting time.  When I connected the phone to the debugger and set up breakpoints, I quickly discovered that InputStream.available () always zero returns! I'm not kidding!

    Our code was constantly diverted waiting, waiting, reading another byte, read a byte...  Even when I changed the way that we on the download time was exceptionally slow (as in "unbearable").

    Worse still - when I tried to wait before making the first longer interval (100ms) read, followed by reading the characters one by one without waiting, the phone started rebooting randomly!

    Request

    Someone has seen something similar?  If so, what was your approach?  I won't sit idly while waiting the answers here - I have a few ideas to try-, but if anyone has been there, it would be nice if you can just push me in the right direction.

    Thanks in advance,

    Arkady.

    Other people have had problems with available().  I'm surprised that you managed to get that you have to be honest, I thought he always returned 0.

    We make socket connections, and always the transmission with a header field that contains prefix length.  So read on the Blackberry is basically

    (a) header to read

    (b) reading of data

    (c) to process the data

    (d) proceed to (a).

    Another user and I had problems recently with http and OS 5.0 using WiFi connections - circuit up to and/or time out when reading the response.  This is the thread

    http://supportforums.BlackBerry.com/T5/Java-development/network-IO-hang-on-OS5/m-p/541487

    I would recommend you change your implementation of socket and detection of data along these kinds of lines, in other words, how data should be read and set up some kind of detection/stall.

    Does make sense?

  • Search for ATG back zero refinements

    Hello

    I implement a search facets in an environment multisite with 3 sites. When I do a search, the number of refinements that are returned by the search in the current site is always zero.

    I tried test search via the search menu Merchandising in BCC, and the same thing happens. The other two sites, refinements are returned correctly, but in the current site, no facets are never returned.

    All facets are Global, so they appear on refinements for each site.

    Any ideas of what could happen? Maybe a setting I'm missing?

    Thank you

    Lucas

    Hello

    Do you have configured/atg/commerce/search/refinement/CatalogRefineConfigAdapter in your research at the CCI environment?

    You must add this component when configuring Pos-Index, in the tab content to your research project.

    Try to check this. If it is not correctly configured, the refinements will not work.

    And you are right when you say that, if the faces are GLOBAL, they should appear for each site.

    It will be useful.

  • GetStat-entity (Cluster) - CPU in real-time - values to zero of the recent time intervals

    Hello world:

    I have a strange behavior when querying via PowerCLI CPU statistics.  We have a handful of clusters in a data center, some with HA + DRS and some DRS only.  PowerCLI seems to report different time intervals (5 min. 20 s vs) according to which cluster is queried and for the most recent 15 minutes of data queries is always zero, although sometimes it's only been 5 minutes which are zero.  This behavior is indicated for applications on clusters and resource pools.

    Is this known behaviour?  vSphere Client shows that the data is present when searching in graphics in real time, so it's confusing why smaller or no value is present at all from the CLI.  Ideally, I would like to know the average use of MHz and percentage for all groups to 20 s averaged granularity on the last 2 minutes, but no amount of massage does seem to happen.

    example query:

    Get-Stat - Realtime-Stat "cpu.usagemhz.average" - entity (Get-ResourcePool-name 'Low') - departure (Get-Date). AddMinutes(-20)-Instance "

    As I understand it, the measures for groups and entities related to the cluster as resourcepools, are aggregated values of definition.

    Which means that the vCenter must calculate these metrics of the values collected by the ESXi hosts.

    In other words there is no interval in real time for the metric for clusters, only of the historical intervals.

  • Difficulty getting on component width dynamic (width is always 0)

    Hello

    I'm a newbie to flex and I was struggling with getting a width on components that I create in AS3 blocks. I have a TileList with a custom ItemRenderer component called ImageRenderer. When a user clicks on one of my articles, I would like to appear on the screen as well as a few other components. I have this work:

    public void onClick(e:ListEvent):void {}

    var i: Image = new Image();

    i.source =. img.source (e.itemRenderer as ImageRenderer);

    var h:VBox = new VBox();

    var t:TextArea = new TextArea();

    h.addChild (t);

    h.addChild (i);

    t.text = "Sample Text";

    h.x = 100;

    h.y. = 100;

    addChild (h);

    trace (h.width, h.height, root.width, root.height);

    }

    I get the Hbox to appear on the screen and displays the image, but the width and height that I get for the Hbox is always zero. Can someone tell me why this happens and how to fix it? I had another similar problem do anything else I ever solved, so perhaps my understanding of how flex calculates the width won't.

    Thank you

    I wonder if your trace is before printing the HBox has time to update its size - because of the asynchronous nature of Flex.  To find out, I put your trace() in a separate method and call this new onClick method using setTimeout(newMethod,500). Will give him half a second set to date. If it's always 0 try changing from 500 to 2000 (2 seconds). If it is still zero after that, then I'm wrong.
