getCurrentRow returns null

• ViewObject getCurrentRow() returns null for a particular VO

  1. I use JDeveloper 12.1.2 and see that one of the VO does not return a current line in the module of the application.

  Table of this VO has an another table foreign key relationship and corresponding EO mapping to a database table is defined.

  I defined the Association and link display to be able to make the key relationship foreign mapping.

  And moved VO belong to the corresponding data model of the parent object.

  However, getCurrentRow running on this instance of VO returns null.

  Runs the code SQL of VO same results as expected in the preview of the VO Editor.

  Can someone further comment on what might cause some getCurrentRow() which returns null despite the lines for VO that corresponds to its definition of SQL or Timo.

  2. one of the posts mentioned earlier setting the following will print the SQL used by VO in the console.

  AddVMOption - Djbo.deguboutput = console

  AddVMOption - Djbo.jdbc.trace = true

  However, my console does not show the SQL code as such to run executeQuery on VO.

  Can someone share your opinion on if these settings are changed in Jdev 12.1.2 charges.

  Thank you

  GetCurrentRow() may return null if the vo is not used in the user interface. In this case, the pointer of the current line is set before the first row so that you can browse all lines.

  After execution of the vo, you must call premier() to get the first row, then next() to get the next line.

• GetCurrentRow returns the null value while trying to values defined in table advanced VO

  Hi all

  I'm trying to set default values to a bean advanced table according to the selection of LOV in another region. Here is the code and getCurrentRow returns the value null and null pointer exception is throwed. Please let me know where Iam going bad.

     if (pageContext. ) isLovEvent ())

  LovInputSourceId = string pageContext. getLovInputSourceId ();

     if ("poNumber". ) is equal to ()lovInputSourceId))

  pageContext . putDialogMessage (new OAException()"inside Onclick"));

  OAViewObject VO = (OAViewObject) am . findViewObject ()"L3APNonprojbasedpoVO1");

  VO1 OAViewObject = (OAViewObject) am . findViewObject ()"L3APCodingInfoEOVO1");

    VO . setWhereClause (null);

    VO . setWhereClauseParams (null);

    VO . executeQuery ();

    VO1 . setWhereClause (null);

    VO1 . setWhereClauseParams (null);

    VO1 . setWhereClause ("1=2");

    VO1 . executeQuery ();

     if (null! = VO )

     Row ReqRow = (Row) VO.first();  

     if (null ! = ReqRow )

     int idx = VO . getRowCount ();

     for (int xx = 0; xx < idx ; xx ++)

  String Description = (String)VO. getCurrentRow (). getAttribute ()"ItemDescription");

     Number Amount = (Number)VO. getCurrentRow (). getAttribute ("Amount");

     String Company = (String)VO. getCurrentRow (). getAttribute ("Company");

  String ProfitCenter = (String)VO. getCurrentRow (). getAttribute ()'ProfitCenter');

     String Dept = (String)VO. getCurrentRow (). getAttribute ("Dept");

     String Lob = (String)VO. getCurrentRow (). getAttribute ("Lob");

     String Account = (String)VO. getCurrentRow (). getAttribute ("Account");

  pageContext . putDialogMessage (new OAException()"inside loops'));

     if (null! = VO1 )

    { am. invokeMethod ("createRow");

  VO1 . getCurrentRow (). setAttribute ()'Description',Description);

    VO1 . getCurrentRow (). setAttribute ("Amount",Amount);

    VO1 . getCurrentRow (). setAttribute ("Company",Company);

    } ReqRow = (Row)VO.next(); }

     else {}

  }

  }

  Here is the method in AM.

  Public Sub createRow()
  {
  
  OAViewObject vo = (OAViewObject) getL3APCodingProjectEOVO1 ();

  vo.clearCache ();
  
  If (!) VO.isPreparedForExecution ())
  {
  System.out.println ("project VO executed");
  vo.setWhereClause (null);
  vo.setWhereClauseParams (null);
  vo.setWhereClause ("1 = 2");
  vo.executeQuery ();
  }
  Line = vo.createRow ();
  vo.insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  
  }

  I modified your code a bit. This code does not require a method of AM.

  If the problem still not solved.

  If you want you can try this and let us know what happens.

  if (pageContext.isLovEvent())
  {
     String lovInputSourceId = pageContext.getLovInputSourceId();
     if("poNumber".equals(lovInputSourceId))
    {
    pageContext.putDialogMessage(new OAException("Inside Onclick"));

    OAViewObject VO1=(OAViewObject)am.findViewObject("L3APCodingInfoEOVO1");
    VO.setWhereClause(null);
    VO.setWhereClauseParams(null);
    VO.executeQuery();
  
    VO1.setWhereClause(null);
    VO1.setWhereClauseParams(null);
    VO1.setWhereClause("1=2");
    VO1.executeQuery();
  
    if (VO != null)
    {
    for( Row ReqRow = (Row) VO.first();  ReqRow != null; ReqRow = (Row) VO.next())
    {
    String Description = (String)ReqRow.getAttribute("ItemDescription");
    Number Amount = (Number)ReqRow.getAttribute("Amount");

    String ProfitCenter = (String)ReqRow.getAttribute("ProfitCenter");
    String Dept = (String)ReqRow.getAttribute("Dept");
    String Lob = (String)ReqRow.getAttribute("Lob");
    String Account = (String)ReqRow.getAttribute("Account");
    pageContext.putDialogMessage(new OAException("Inside for Loop"));
  
    if (VO1 != null)

• VO.getCurrentRow () returns a null value

  Hi, OTN
  
  In short, the scenario is:
  View object is based on an entity. There is a form to the JSF page.
  I select a record by clicking next and previous. Then I click on create to display empty fields for the new record.
  When I click on the button, I need to register a field value and a default value for the new fields to records.
  
  How to:
  I have created a support bean and added customCreateMethod. To start, I want to get the value of current row field, but I can't get the current line.
  
  public String customCreateMethod() {}
  
  String amDef = "pattern. AppModule. "
  Config = "AppModuleLocal";
  
  Am = ApplicationModule
  Configuration.createRootApplicationModule (amDef, config); non-null
  
  ViewObject vo = am.findViewObject("ContentVersionView1"); non-null
  
  
  = problem here:
  vo.getCurrentRow (); Returns a null value
  
  System.out.println ("index:" + vo.getCurrentRowIndex ()); always returns 0
  }
  
  I tested variable vo by this code:
  
  While (vo.hasNext ()) {}
  Line = vo.next ();
  System.out.println (Row.GetAttribute ("IdContent"));
  }
  
  It works fine.
  
  
  How should I me current line?
  
  Thank you

  Hello

  createRootApplicationModule creates the new instance of the application module, thanks to which you did not receive the current line. Use the code posted by Timo in [this post | http://forums.oracle.com/forums/thread.jspa?threadID=933022] (which has been marked as correct) to get the instance of module of the application.

• getAttribute() method of a view object returns NULL

  Hello
  I am currently implementing PPR in one of my OFA page and I took the following approach.
  
  I stated the Boolean attribute transitional follwing in the VO() outside of the existing attribute 'sense '.
  1 MfgEnttity
  2 MfgAcct
  3 MfgSubAcct
  4 MfgCc
  5 MfgProj
  
  In the page I used these attributes in the property made in the form "${oa." XXR2RMfgproSegVO.MfgSubAcct}' like that.
  
  Now, in the central, I wrote the following code.
  
  ' Public Sub processRequest (pageContext OAPageContext, OAWebBean webBean)
  {
  super.processRequest (pageContext, webBean);
  OAApplicationModule am = pageContext.getApplicationModule (webBean);
  am.invokeMethod ("initializeXXR2RMfgproSegVO");
  }
  ' Public Sub processFormRequest (pageContext OAPageContext, OAWebBean webBean)
  {
  super.processFormRequest (pageContext, webBean);
  
  Event string = pageContext.getParameter (EVENT_PARAM);
  Source of the string = pageContext.getParameter (SOURCE_PARAM);
  Am = (OAApplicationModule) pageContext.getApplicationModule (webBean) OAApplicationModule;
  am.invokeMethod ("handleSegmentChangeEvent");
  }
  }
  
  
  And the AM code is as follows:
  
  Public Sub initializeXXR2RMfgproSegVO()
  {
  OAViewObject vo = getXXR2RMfgproSegVO();
  If (!) VO.isPreparedForExecution ())
  vo.executeQuery ();
  Line = vo.createRow ();
  vo.insertRow (row);
  row.setNewRowState (Row.STATUS_INITIALIZED);
  }
  
  Public Sub handleSegmentChangeEvent()
  {
  PVO OAViewObject = (OAViewObject) findViewObject ("XXR2RMfgproSegVO");
  OARow hdrRow = (OARow) pVO.getCurrentRow ();
  String status = (String) hdrRow.getAttribute ("Meaning").
  System.out.println ("poRow" + hdrRow.toString ());
  System.out.println ("value of the State is" + status);
  If ("Entity". Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.TRUE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ("Account". Equals (Status))
  {

  hdrRow.setAttribute ("MfgAcct", Boolean.TRUE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);

  } else
  If ("Subaccount". Equals (Status))
  {

  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.TRUE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ("cost Center".equals (status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.TRUE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  } else
  If ('Project'. Equals (Status))
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.TRUE);
  }
  on the other
  {
  hdrRow.setAttribute ("MfgEnttity", Boolean.FALSE);
  hdrRow.setAttribute ("MfgAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgSubAcct", Boolean.FALSE);
  hdrRow.setAttribute ("MfgCc", Boolean.FALSE);
  hdrRow.setAttribute ("MfgProj", Boolean.FALSE);
  }
  }
  }
  
  Now when I change in the value of the attribute "Meaning" page that he can always get into the else part, which is where all the attributes are 'False'.
  
  The two System.out.Println statements return the following values.
  
  03/10/22 15:41:08 poRow xxr2r.oracle.apps.gl.coam.poplist.server.XXR2RMfgproSegVORowImpl@3
  03/10/22 15:41:08 state value is null
  
  Can you please why this 'status' returns NULL and how I can get the current selected line in the page?
  
  Thank you
  Lucile

  Hello

  you set the attributes of PVO, based on a condition, your old code is just the question is from where you can get the status, you may get this page, but you must pass this value to AM.

• PersistentObject.getContents () returns null after app update

  Hello

  I'm trying to track down a bug with PersistentStore.
  Usually when I update the app I get the getContents() stored content.
  However, something in the code has changed from one version to the other and now getContents() returns null.

  I made sure the id has never changed for PersistentStore.getPersistentObject (id);
  I made sure that we use the same basic sdk (4.3.0)
  I made sure that there are the data stored in the stored hash table

  Currently, it's a hash table - no subclass (even though I know that I should change it to a subclass when it's fixed);

  I wonder if there are any suggestions on what might cause the getContents() return null - or which could result in the PersistentStore have cleared.

  What information is needed, please let me know and I'll paste.

  I found the problem after.

  Classes have begun to obscure differently. If the hash table was still readable, but because he could not read the content of the hash table, he would return null.

  It was unexpected, because if you have a custom class persisted and you try to read it, you will get the content, but you can't cast. But with the hash table, it does not return the content (uncastable) and it throws no exceptions...

  I hope this helps someone else who has a similar problem.

• The body of the message to return null on os 4.5.0.18. When you use getBodyText()

  Hi all

  Today, when I debug my application on 4.5.0.18 device 8130.

  I implements FolderListener, when new messages coming,.

  I grap message object and want to analyze the body of the message to check if the message is what application you are looking for.

  Hoever, when I call Message.getBodyText (). It returns null.

  In fact, there a lot of message in the body of the message.

  is there any sweet experiencing this problem?

  What is work around?

  Thank you.

  getBodyText() will work on 4.5 If the body is 'plain text '. Otherwise, you will need to get the HTML content of the message and extract the text elements.

• Hash table returns null

  It's the stumping me. I add a key and a value in a hash table, pass in the key and retrieve the value. Basic enough, but when I go to retrieve the value a second time (after the restart of the application), it returns null.

  If it isn't exactly the code that would be the basic scheme:

  class A
  {
       private static Hashtable table = new Hashtable();
  
       public static Object getObject(Class clazz)
       }
            return A.table.get(clazz);
       }
  
       public static void setObject(Class clazz, Object obj)
       }
            A.table.put(clazz, obj);
       }
  
       //Code stuff...
  }
  
  class B
  {
       public static void main(String[] args)
       {
            A.setObject(C.class, new C());
            Object obj = A.getObject(C.class); //This works
       }
  
       //Code stuff...
  }
  
  class C
  {
       //Code stuff...
  }
  

  What happens on the 9550 Simulator and is fixed after restarting the Simulator but work always and only the first time through. If the app is closed, then reopened, then it returns null, even if the hash table was always the same items.

  Ah. When you run the application a second time, he rebuilt serializers to persistent store. Unfortunately, your objects of the class are new instances, so that they cannot be used as persistent hash keys. I suggest you use class names as keys rather than objects of class themselves.

• Need help with ics. SQL return null

  Hi experts WCS.

  I have this ics. SQL statement that returns an IList as null and nothing in the errStr in debugging print.

  IList rsATypes is ics. SQL (, sqlATypes, listName, limit, bCache errStr);

  The code is in one of my jsp. He ran very well in my local JSK (HyperSQL Db), but returns NULL in the case of Test (Oracle DB, if this is another).

  I got the sql statement println during execution and run it directly in Oracle DB (same instance) it returns the expected result set.

  The code snippet:

    System.out.println("## ics.GetSSVar(\"pubid\")          : " + ics.GetSSVar("pubid"));
  
      // Get Attribute Types
      String sqlATypes = "SELECT DISTINCT assetpublication.assettype "
                       + "FROM assetpublication "
                       + "LEFT JOIN approvedassets "
                       + "    ON assetpublication.assetid = approvedassets.assetid "
                       + "WHERE pubid = '" + ics.GetSSVar("pubid") + "' "
                       + "AND (tstate is null OR tstate <> 'A') "
                       + "AND (voided is null OR voided <> 'T') "
                       + "ORDER BY assettype; ";
      System.out.println("##0126 sqlATypes : " + sqlATypes);
      String from = "AssetPublication, ApprovedAssets";
      // String listName = null;
      String listName = "ATypesList";
      int limit = -1;
      // boolean bCache = true;
      boolean bCache = false;
      StringBuffer errStr = new StringBuffer("");
      ics.ClearErrno();
      IList rsATypes = ics.SQL(from, sqlATypes, listName, limit, bCache, errStr);
  
      System.out.println("## rsATypes : " + rsATypes);
      if (rsATypes == null) {
          System.out.println("## NO DATA in rsATypes! errStr : " + errStr.toString());
  

  }

  The journal:

  ## ics.GetSSVar("pubid")          : 1374097570685
  ## sqlATypes : SELECT DISTINCT assetpublication.assettype FROM assetpublication LEFT JOIN approvedassets     ON assetpublication.assetid = approvedassets.assetid WHERE pubid = '1374097570685' AND (tstate is null OR tstate <> 'A') AND (voided is null OR voided <> 'T') ORDER BY assettype;
  ## rsATypes : null
  ## NO DATA in rsATypes! errStr :
  

  
  

  I got enclosing try catch block, who did not take any exception.

  
  

  The funny thing is, in the same piece of code, an ics. Casea used already worked (which I noticed outside because there was not enough for what I want to do):

          StringBuffer errSB = new StringBuffer("");

  Thanks Guddu1223, I discovered why.

  The SQL statement cannot end with a semicolon (see line 11 of my original above codes). Delete who had back all the records provided for in my resultset in the IList.

• DataBind method call returns null in the WebCenter content filtering

  Hello

  I got code that has a problem and I am new to the WebCenter content and filters that can be added. We have a FileNameFilter class that begins with the code

  }

  However, service is sometimes return null and then filter throws a NPE.

  My questions are:

  (1) can we explain what dataBinder.getLocal ("IdcService"); is done and why it might come back as null

  (2) anyone can provide links to documentation that explains the filters and a little more on the object DataBinder as the JavaDoc is not much help.

  Thank you

  Hi Marc,

  If String = dataBinder.getLocal ("IdcService") service; Service = "DOC_INFO_BY_NAME."

  Under blog will give an idea about the filter but the best place to learn or start is "The Definitive Guide to Stellent Content Server Development" by Brian Huff

  Also, I recommend reading ' WebCenter Content Services Reference Guide '

• APEX_ITEM. DATE_POPUP returns NULL Version 4.2.6

  I apologize in advance if I'm misunderstanding here, but should not return the following query a few HTML, etc. ?

  SELECT APEX_ITEM. DATE_POPUP (1, rowNum, to_date(sysdate,'DD-mm-YYYY'), 'DD-mm-YYYY') date_html

  OF the double

  I am confirming my queries through SQL Developer first and then plan to add to a report of the APEX for a manual form.  APEX_ITEM. TEXT Returns HTML can be used in SQL Developer, but I can't understand why APEX_ITEM. DATE_POPUP returns NULL regardless of any parameter combinations I try.  Thanks in advance for the answers.

  Do not apply to_date conversion sysdate . It's already a DATE value.

  It is the expected behavior. Some API calls can be used successfully since in a valid session of APEX. You can validate apex_item.date_popup query in the APEX SQL Workshop. Note that apex_item.date_popup2 is the recommended method because it shows a more modern jQuery calendar.

• Debugging inaccessible FacesException:Target, 'bean' returned null

  Hi all

  Jdev: 11.1.1.7.1

  We have a living ADF application that worked very well until installing a recent where a flow is the break with the message "inaccessible FacesException:Target, 'bean' returned null. It works very well in our UAT and our production environment is clustered.

  StackTrace

  oracle.jbo.JboException: JBO-29000: Unexpected exception caught: javax.faces.FacesException, msg=#{pageFlowScope.xyzBean.showCaseDetails}: Target Unreachable, 'xyzBean' returned null

  Guidance on how to debug what appears not a problem with scope as our UAT works very well.

  We were finally able to reproduce the problem in our local instance.

  Regarding the cause, the view behind the UI object, the research doesn't have the right keys. As a result, selection on the table was selecting two rows on the search results. By clicking on the commandlink, it seems that two events of Action are put in queue and after that the first action event navigates successfully, the second is pulled and fails.
