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 null

    Hello

    I have a problem with vo.getCurrentRow ().

    I try to call the vo.getCurrentRow () of my application module after I booted my query and run executeQuery() in my implementation of the view object.

    The problem is that it returns null - although I'm sure that the request actually extracted (exactly) a line.

    ...
    OAViewObject vo2 = (OAViewObject) getEngineerDetailsVO1 ();

    If (vo2.getRowCount () > 0) {}
    Line line (Row) = vo2.getCurrentRow ();
    ...

    When I debug the code, I see that I get to this declaration, but row evaluates to null. Why?

    Hope some of you have experienced this problem and can respond easily.
    Thanks in advance.

    Because the record pointer can be points on any line.

    Try with Row row = (Row) vo2.first (); if you want to get the first record.

  • 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.

    It works fine.


    How should I me current line?

    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.

  • 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 ())

    Here is the method in AM.

    }
    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.

  • 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:

  • A query to return all the SQL executed for a particular user instructions.

    Hello

    Is it possible to find all the instructions SQL for a particular user using the views v$? I can do it 10g but I am currently using 9i, the query below does not work.
    select a.username,a.logon_time,b.sql_fulltext 
from v$session a,v$sqlarea b 
where a.sql_id=b.sql_id
and a.username='USER'
order by a.logon_time desc
    I guess that some columns in these views do not exist in 9i. The output of 9 that I use is 9.2.0.1.0.

    Your help is very appreciated.

    Thank you
    Select this option.

    Dear mark!

    I suggest you use the audit instead of v$ sqlarea. Onlinedocumentation said the next thing Oracle v$ sqlarea:

    >
    V$ SQLAREA lists statistics on the shared SQL area and contains a line by the SQL string. It provides statistics on SQL statements that are stored, analyzed and ready for execution.
    >
    This means that you will only get the SQL statements that are currently in memory. Older statements which are already deleted from memory are not visible for your query.

    Incidentally, if you simply want to know what's wrong with your query then please post your errormessage.

  • request (?) featured: matrices or tables for a particular column sort

    Hello all-

    This may be a stupid question, because I'm always still not quite clear on what are the differences between the matrixes and 2D arrays in LabView. So far the only distinction I seemed to find, it is that certain features of table return errors when the matrices are entered and vice versa.

    Anyway, here's my question.

    Suppose I have a matrix where the first column represents the 'values' that have been measured and the second column 'account'. I would like to take a unordered matrix (i.e., the value column is not ordered) and recover a matrix that has had its lines re-arranged according to the values in the first column.

    For example, if my matrix:

    [5-1;

    0 11;

    1-5;

    3-10]

    I would like to as labview to return:

    [0-11;

    1-5;

    3-10;

    1 of 5]

    When I was trying to find a way to do it (without writing my own sorting routine which, admittedly, wouldn't be too bad, but I'm a lazy programmer ), the only thing I found that came close was the 'matrix of D 1 sort' Subvi. However, even if I had to store the values in a table and charges in another table, I'd be able to do is sort the table values. I wouldn't be able to tell what labview reorganization, I would need in order to perform the same reorganization charges.

    I'm a little surprised that there isn't a quick and intuitive way to do this (at least that I can find). A LabView feature addition that could help with this problem would be if the "1 D Array sort" routine returned a second output - a vector with the mapping of the index used - similar to MATLAB. MATLAB help for the function 'out ':

    "[There, I] = SORT(X,DIM,MODE) also returns a matrix of index I.. «If X is a vector, then Y = x.»

    Of course, there may be a quick fix for what I'm missing...

    Take a look at this post. I don't know that you can change for your particular type of data.

    (in contrast to the first colum, create the sort key, table 2D reconstructed according to key)

  • 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.

  • 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("");
        ics.SetVar("assetid", id);
        IList approvedAsset = ics.SelectTo("ApprovedAssets", "state,voided,tstate,locked,reason,treason", "assetid", null, -1, null, true, errSB);

    Hello

    If you need to do this in SQL, and then use an expression BOX to return deptno for the first line of each deptno and NULL for all others.  ROW_NUMBER can determine which is the first line, like this:

    Select

    CASE

    WHEN ROW_NUMBER () OVER (PARTITION BY deptno

    Sal of ORDER BY DESC

    )  = 1

    THEN deptno

    ANOTHER NULL - Default; can be omitted

    END AS deptno

    ename, sal,

    ROW_NUMBER()

    courses (deptno partition

    order by sal desc) rn,.

    Rank()

    courses (deptno partition

    order by sal desc) rnk.

    DENSE_RANK()

    courses (deptno partition

    order by sal desc) drnk

    from scott.emp

    order by EMP. DeptNo, sal desc

    /

    Notice how I used emp.deptno in the ORDER byclause in the query.  Simply deptno in this place means that the results of the CASE, not the original column expression.

  • 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

    / public class CWEFileNameFilter implements FilterImplementor {}

    public CWEFileNameFilter() {}

    Super();

    }

    public int doFilter (workspace workspace, DataBinder dataBinder,

    ExecutionContext executionContext) throw {DataException

    Service string = dataBinder.getLocal ("IdcService");

    ....

    }

    }

    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
    Marc

    Hi Marc,

    Below the code will give the name of the service for which the filter is implemented LocalData

    Service string = dataBinder.getLocal ("IdcService");

    for example below

    http://localhost:16200/cs/idcplg? IdcService = DOC_INFO_BY_NAME & dDocName = 1111111 & IsJava

    This example displays the entire response including localdata data and results that are created in the execution of the service. Here is the code snippet

    LocalData @Properties

    DocUrl =https://localhost:16200/cs/weblayout/groups/secure/documents/test/mhdk/mjg1/1111111.pdf

    IdcService = DOC_INFO_BY_NAME

    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

    http://www.redstonecontentsolutions.com/technical-blog/UCM-service-handlers-and-javafilters

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

    http://docs.Oracle.com/CD/E23943_01/doc.1111/e11011/TOC.htm

    Kind regards

    Amol Germain.

  • 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.
