NullPointerException trying to ViewObject.setCurrentRow(Row)

JDev 10.1.2 build 1811 ... JClient app
Basically, I'm attempting to save and restore a view's currency before and after clearing the entity cache of one of its entities.
The code is executed in the event thread (later) in beforeSetAttribute if that matters.
    DetailAM detailAM = (DetailAM)panelBinding.getApplication().getApplicationModule();
    ViewObject view = detailAM.findViewObject("ASP20_AssortmentItemView1");
    Row row = view.getCurrentRow();
    Transaction transaction = detailAM.getTransaction();
    transaction.postChanges();
    transaction.clearEntityCache("dg.merchandising.asp.detail.model.AssortmentVendorItem");
    view.setCurrentRow(row);I have checked that the row object is not null and its key is not null.
[java] Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
[java]      at oracle.jbo.server.ViewRowSetIteratorImpl.setCurrentRow(ViewRowSetIteratorImpl.java:950)
[java]      at oracle.jbo.server.ViewRowSetImpl.setCurrentRow(ViewRowSetImpl.java:2552)
[java]      at oracle.jbo.server.ViewObjectImpl.setCurrentRow(ViewObjectImpl.java:6159)
[java]      at dg.merchandising.asp.detail.swing.ASP20.restoreCurrency(ASP20.java:2854)
So is what I am attempting simply an invalid operation since I am clearing the underlying cache without revalidating the cache somehow?

Using JUIteratorBindings on top of the views, saving the keys, then using JUIteratorBinding.setCurrentRowWithKey(String) seems to work. So far, so good, anyway.
Perhaps a more informative exception could be raised instead of a NullPointerException thrown from the source-unavailable bowels of ADF if you try to ViewObject.setCurrentRow with a bad Row object.

Trying to omit duplicate rows in a UNION

I am trying to omit duplicate rows from my union’ed join of 2 tables but am running into a problem which I am hoping someone can help me with. The following SQL works, but doesn’t omit the dups.
SELECT service_code, description_txt, effective_date, ROW_NUMBER() OVER (PARTITION BY service_code
ORDER BY effective_date DESC) AS rn
FROM
(SELECT s.service_code, s.effective_date, s.description_txt
FROM state_code_desc s
WHERE s.expire_date IS NULL
AND s.code_type='H'
AND s.coverage_type='W'
AND s.geo_area_code='USA'
AND s.state_abbr='GE'
UNION
SELECT f.service_code, f.effective_date, f.description_txt
FROM fed_code_desc f
WHERE f.code_type='H'
AND f.expire_date IS NULL
ORDER BY service_code
When I try to add the WHERE RN=1 immediately before the ORDER by service_code (last line of the SQL), I get the following error:
ORA-00904 – “RN” Invalid identifier
Can someone out there help me out, please?
Thanks!

P.S.-I'm running Oracle 9.1

Just a precesion,
It is not a question of analytic functions at all
In fact, column aliases are not usable in tbe same

JTable - trying to delete a row of data using an Abstract TableModel

Hi Guys,
I am trying to delete a row of data on a JTable. What I am trying to accomplish is to highlight the row by a mouseclick,
then from the menu bar I am having the user select a "delete row" option. I am working with an abstract
Table Model with a deleteRow method. I know I am doing something wrong in this method but I'm not sure what... it is not deleting nor dynamically reflecting the deleted row of data on the JTable gui:
P.S. I am using a Vector of Vectors to store the data
Here are snippets of my main class and Abstract Table Model :
Main Class
Table definition and mouse listener:
usermodel = new DataFileTableModel("UserCtl.dat") ;
userTable = new JTable();
userTable.setModel(usermodel);
userTable.createDefaultColumnsFromModel();
userTable.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent evt) {
upoint = evt.getPoint();
rowToBeDeleted = userTable.rowAtPoint(upoint);
Menu Selection which calls the deleteRow Method in the model:
deleteitem = new JMenuItem("Delete Row",'D');
editmenu.add(deleteitem) ;
deleteitem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int delresp = JOptionPane.showConfirmDialog(null,"Are you sure you wish to delete this row ?",null, JOptionPane.YES_NO_OPTION) ;
switch(delresp) {
case JOptionPane.NO_OPTION:
return;
case JOptionPane.YES_OPTION:
switch (tabnum)
case 0:
usermodel.deleteRow(rowToBeDeleted);
break ;
Here is my Abstract Table Model... the deleteRow method is at the bottom:
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.event.*;
import java.io.*;
import java.util.*;
public class DataFileTableModel extends AbstractTableModel {

// extract data

while(st2.hasMoreTokens())
data.addElement(st2.nextToken());
br.close();

fireTableCellUpdated(rowIndex, columnIndex);
public void addRow(Object[] aRow) {
for (int i=0; i < aRow.length; i++)
data.add(aRow);
int size = getRowCount();
fireTableRowsInserted(size-1,size-1);
public void deleteRow(int rowNo)
 if (rowNo < 0 || rowNo >= getRowCount())
 return;
 int colCount = getColumnCount();
 int index = colCount * rowNo;
 System.out.println("in deleteRow Row = " + rowNo);
 System.out.println("colCount = " + colCount);
 System.out.println("index = " + index) ;
 for (int d = index; d <= colCount; d++)
 data.remove(d) ;
 fireTableRowsDeleted(rowNo,rowNo) ;

Hi,
I can see one obvious problem. Your method to delete contains
for (int d = index; d <= colCount; d++)
data.remove(d) ;
which I think should be
for (int d = index; d <= colCount; d++)
data.remove(index) ;
because every time you remove the value at 'index' it replaces it with the value at 'index+1'.
I'm not sure that this is the only problem but ...

ViewObject with rows not based on a query

Hello,
I have an ViewObject with rows not based on a query. For example, if in activate method from my application module I insert a row, that row will not show when I test my app module. Please do not answer with a link for SRDemo ADF+BC as i've read it and didn't find any answers there.

Yes,thanks, I found that, but I don't know how to do a ViewLink that have as destination a viewobject like that. I get all rows from destination for any row from source. There is a way to do that?

Thank you for the reply.
Steve,
Pardon me if this is an obvious question, but is
SUBMIT_REFRESH_ACTUALS a
PL/SQL function?Yes.
According to what you have posted,
the call spec for
SUBMIT_REFRESH_ACTUALS should be:
function SUBMIT_REFRESH_ACTUALS (PARAM number)
return number;Is this correct?Yes.
CREATE OR REPLACE FUNCTION submit_refresh_actuals
(p_plan_id ASSORTMENT_PLAN.PLAN_ID%TYPE)
RETURN NUMBER
where ASSORTMENT_PLAN.PLAN_ID's type is NUMBER(10).
Have you tried executing the function in
SQL*Plus? For example:
select SUBMIT_REFRESH_ACTUALS(1) from DUALGood Luck,
Avi.The DB guy here is telling me:
I can't because it does DML inside the function, but it works fine inside an anonymous block.

Remove the closing slash in this tag.

I am sure you meant to close it with the </jbo:Row> some lines below.
That explain the complaint of the setAttributeTag missing their context.

Issue with parameter/filter - trying to display null rows

This is how my data looks in the database
Order_ID ----- Vendor
ID123 NULL
ID234 ABC
ID456 NULL
ID001 CDE
I want to create an SSRS report with a filter for vendors
*All Vendors should be checked off by default
*Users should be able to select multiple vendors
So I started by creating the VendorDataSet, the query looks like
SELECT VendorName
FROM Vendor
WHERE Active = 1
*This query will return all active vendors stored in my vendor table
Then, I created my parameter @prmVendor and it looks like:
-Data Type: Text
-Allow blank value("")
-Allow multiples values
Available Values:
-Dataset: Vendor
-Value field: vendor_name
-Label field: vendor_name
The main query of the report looks like
Select Order_ID, Vendor
FROM Order
LEFT JOIN Vendors
ON Order.VendorID = Vendor.ID
WHERE Vendor IN (@prmVendor)
So at this point it does what is supposed to do except - that when I run the query with all the vendors selected,
the query will only return the ones with vendors populated.
Order_ID ----- Vendor
ID234 ABC
ID001 CDE
I've tried adding the following to my VendorDataSet:
SELECT VendorName
FROM Vendor
WHERE Active = 1
UNION ALL
SELECT '' -- I've also tried SELECT NULL
But when I run the report and look at the list of vendor displayed - it won't show the empty row in the vendor drop down filter
thus, my main query will ignore the orders with no vendors.
Any ideas on how to fix this issue?
-Alan

So I changed my VendorDataSet to look like this:
;WITH cteVendors AS (
SELECT VendorName
FROM Vendor
WHERE Active = 1
UNION ALL
SELECT ''
SELECT (CASE WHEN Vendor IS NULL THEN '' ELSE Vendor END) AS VendorName
FROM cteVendors
This allowed me to show an empty box in my drop down filter see link for
image
Is there a way to make some changes to my main query so this works? so if the user was to select the blank box the query will return something like :
Order_ID ----- Vendor
ID123 NULL
ID456 NULL

Trying to fetch a row ID from the address bar

Hello,
I am creating a website that will strickly be run on a touch
screen and saved locally. I am using spry.
I have a Category page with a list of 4 products (Each a
large link button). All of them link to the same html document like
so:
href="product.html?thisID=0" and then the next one "thisID=1"
and so forth.
On the product.html page I wrote a little javascript function
to read the address bar and get me the id number. Here is the
javascript function that runs on page load:
function fetchID() {
var varArray = document.location.href.split("?");
var thisID = varArray[1].split("=");
dsProducts.setCurrentRowNumber(thisID[1]);
alert(thisID[1] + " | " + dsProducts.getCurrentRowNumber());
When I click the first product with thisID=0 the alert says
"0 | 0"
And spry gives me an error saying "Invalid Row Number: 0"
When I click on the second product (thisID=1) the alert
correctly says "1 | 0" and once again I get an invalid row number:
1
How can I set the current row using the variable in the
address bar? My javascript correctly gets me the integer that I
pass.
Thanks,
Braxo

Hi Braxo,
To do what you want is no need to parse the whole url to get
the id number.
You can add an observer for your dataset. When the dataset
will be populated with the values from xml, you can set the current
id to the url parameter.
You have to this because when page loads and your code runs
no data is present . This is because data loads asynchronous.
You should add something like this into your code:
dsProducts.addObserver({ onPostLoad: function(ds, type) {
dsProducts.setCurrentRow(params.thisID); }
Until the end of this week, on labs will be posted an
complete example that covers your situation and you can follow the
example from there.
Hope this helps,
Diana

Java.lang.NullPointerException trying to migrate from MySQL to OracleXE

(Originally posted in the SQL Developer forum)
I'm trying to migrate a small MySQL database (four tables) to OracleXE. When I capture an object (table, schema or entire database), I'm receiving a java.lang.NullPointerException message from the Capture source in the Migration Log window. The migrated object doesn't show up in the Captured Objects window until after I shut down SQL Developer and restart it, then the tables in the migration script don't have any columns defined in them.
Here's the error from the console:

There's a known bug in the code that captures 4.1 MySQL databases (specifically). The fix has been applied, and will be available in our next release.
for a temporary workaround, you can put your data into a MySQL 4.0 or 5.0 database.

Thanks for the reply.
I have the following ones:
commons-beanutils.jar
commons-collections.jar
commons-digester.jar
commons-el.jar
commons-logging.jar
el-ri.jar
jsf-api.jar
jsf-facelets.jar
jsf-impl.jar
jstl-1.2.jar
myfaces-api-1.1.3-SNAPSHOT.jar
myfaces-impl-1.1.3-SNAPSHOT.jar
The funny thing is, that the app runs fine at home with the same versin of Eclipse/Tomcat but not over here at work. Both are Devel environments running Windows XP. Also tried to run on Tomcat 6 in linux and got same null pointer.
Any idea which jar it can be?

Essbase Adapter problem, NullPointerException trying reversing

Hi, i'm trying to import via ODI some data in Essbase.
I've imported the adapter, the RKM and created the dataserver and phy schema.
When in designer i try the reverse engineering i obtain a java.nullPointerException.
I've also added drivers path to windows enviroment.
I think there is an error in DataServer settings.
I've filled in as follow:
name: essbase name (taken by essbase console)
user and pass: demoadmin (it's local admin)
In Phy Schema i've written the name of application (OdiLoad) and Database (DataB) for both catalog, work and schema fields.
I don't know how test where is the error.
Edited by: DecaXD on 28-ott-2008 4.21

The operator list is blank. This is due probably because i can't interface to Essbase server. Once i succeded to started session and i obtained this same problem
Re: Reverse Engineering of Essbase cube failing
when i start reverse i obtain a nullPointerException

its already works and the row with 0 is set to red but when i try to select any cell in the table

hi again camickr
i changed the stopCellEditing as you mentioned
changed the getCellEditorValue to return an integer
and give exception and error message if the value can't be converted into integer(non numeric)
but the problem is when i run the program and change the value in any cell with numeric values
or with non numeric or not changing the value and press enter
it give the error message meaning it cannot convert the value to integer
even if enter an int or don't change the value ????????

LOV throws NullPointerException when there are no rows to display

Hi,
I have cascading LOVs in my application. I have 3 of them. I select values for the first 2 LOVs, and then I click on the 3rd LOV. The query for the third LOV returns no records from the database and so, a NullPointerException is thrown.
When there are no rows to display in the LOV, I want the LOV to still pop up with a message saying "No rows to display".
Is there a way I can achieve this functionality using the existing features?
I am using JDev 11.1.1.3.0
Thanks
