Is Not Null Validation does not work

I have a simple form with contact information (name, phone number, title, email address). The phone number is made up of 3 fields (area, phone_1, phone_2). All fields are required. When all 3 fields of phone are entered, i still get the 'Area Code' must be specified. It is there. What am I not seeing?
Can someone help? This seems so straightforward. What am I missing??
Robert

Robert,
I disabled the on-load processes so you can run page 39, enter form values, submit the page, and see validation errors (or no errors).
I think the validation is okay. Check the source and source type values for P39_CONTACT_AREA. The source refers to a non-existent page item, as seen in the page export:
p_source=>'SUBSTR(:P39_CONTACT_PHONE,1,3)',
Also, the Source Type Function should probably be PL/SQL Expression.
Similar problems with the other phone components.

Apex 4.1. cannot see the details of not null validations generated by apex

Hi there,
I have worked with APEX 3 quite a while. Now I move to new place, and they use APEX 4.
I am currently doing the Advanced Tutorials - Issues Tracker (written for 3.2 ) on an APEX 4.1.
I am quite impressed with a lot of enhanced features of APEX 4.
However, I think I got quite confused about the NOT NULL vaildations.
In the tutorials, they said when creating a form based on a tablle of which the columns have NOT NULL constraint, it will automatically generate NOT NULL validation.
But when I extend the validation section (in both Component View and Tree View), I cannot see any vaildation there.
So I go a head and create some NOT NULL validations for all NOT NULL fields.
Guess what, when I test the form, I got duplicate error messages.
I get these
6 errors have occurred
Project Name must have some value. (Go to error)
Start Date must have some value. (Go to error)
Target End Date must have some value. (Go to error)
Please provide project name. (Go to error)
Please provide project start date. (Go to error)
Please provide target end date. (Go to error)
My validation has error message "Please provide project name" while the automatic one has "Project Name must have some value".
The issue is I cannot find where the automatic validation is.
What if I want to customise the error message rather than just "#Label# must have some value".
Do any of you have any ideas why ?
I guess I must have chosen something wrong during page generation.
It could be quite simple but I don't know where to find the place that turn on/off the automatic not null validation, or at least customize these automatic error messages.
I currenly develop the application using workspace admin account.
Thanks a lot in advance.

I found it. Turn out to be the Settings, choose No for Required Value.

Why validation does not occur if record status is NEW?

Hello! I have a control block MAIN with PORT item in it, which has Required property set. But when I enter that block and pass through this PORT item, it allows me to leave that item blank (and validation does not occur too), which is not what I need.
However, if I change some other item's value (and record status becomes INSERT), validation works as expected. So, I have one workaround for my problem, but this solution is not good.
How can it be fixed? Thanks in advance.

It looks like the documentation is lacking in this situation. But the documentation has always been less than complete.
On-line help also states:
    Note: if the validation is as a result of a
    call to the VALIDATE trigger and the
    record's internal status is New, the process
    stops.So it does mention records with status=New, but it does not give you the complete story.
Dave's explanation is correct, and his solution of setting the field in a when-new-record-instance trigger is as good as it gets.

How to create a single 'not null ' validation for all the items in a page ?

Hi everyone ,
how to create a single 'not null ' validation for all the items in a page ? I have many textfields . Instead of creating 'not null' validation for each item , I would like to create a a single validation control that will serve the purpose
Thanks & Regards

bob , as u said I have done the following :
1) under create button , there are 9 items and for each item I have set Required to 'Yes'
2) under delete button , there is 1 item and have set Required to 'Yes' for the item
3) defined page validation for 9 items under 'create ' button and have set it to fire when 'create ' button clicked
4) defined page validation for 1 item under 'delete ' button and have set it to fire when 'delete ' button clicked
now , when I click 'create' button it even shows for the item under 'Delete ' button that it is a required itemSorry, I didn't see this note. The required template won't work, there is no way to attach it to the button.
The best solution is as the reply a couple replies up
Create 2 page type validations as a PL/SQL with code
1st validation
:P1_ITEM1 IS NOT NULL and :P1_ITEM2 IS NOT NULL ...... and :P1_ITEM9 IS NOT NULL include all 9 items
Set the When Button Pressed to the CREATE button
2nd validation
:P1_ITEM10 IS NOT NULL
Set the When Button Pressed to the DELETE buttonI think that's going to be the easiest way to do it.

Symptom
It is not possible to add or update marketing documents if an item has a value in the Country of Origin field. The application displays the following error message: "Country of origin not valid; country of origin is not allowed or does not exist".
Reproducing the issue
Prerequisites:
Your company database is not in the Russia localization or you have not enabled the Intrastat feature that is relevant to EU countries only.
Scenario:
1. Create or update an item using the DI API. Specify a value for in the Country of Origin field. (Note that this field is not visible in the application).
2. Try to create a marketing document (that is, an invoice using this item).
Actual behavior:
The document cannot be added and the application displays the following error message "Country of origin not valid; country of origin is not allowed or does not exist".
Expected behavior:
The document can be added.
Cause
Application error
Solution
WORKAROUND:
Update the affected items using the DI API as follows:
1. Run the following query to identify the affected items:
select CountryOrg, * from oitm where CountryOrg is not null
2. In the Country of Origin field, set a blank value.

The wish list only works on apps you have to pay for. To get it tap the icon of the app you want to save. After it opens at the upper right corner is a box with a arrow. Tap that then tap add to wish list list in the box that opens.

Validity does not lie in selected validity window.

Hello All,
We have some Z condition created in SAP CRM. We are maintaining the price list for ZLPT condition in General Condition Maintenance.
But if we put today's date or any past date in Validity from then record is getting saved. but if i entered future date in valid from then its giving error Validity does not lie in selected validity window.
The price for that some records is going to change after 2 months, so we want to maintain it now in GCM.
Thanks in Advance.

According to the book I'm reading, if you merely take
out the generic from the code, it should compile and
run in v1.4 (assuming, of course, that the class
exists in 1.4). I don't know what book you are reading but that's certainly incorrect or incomplete at least. I've manually retrofitted code to 1.4, and you'll be inserting casts as well as replacing type references with Object (or the erased type, to be more precise).
These interfaces do exist in 1.4, and
without the generics.Exactly. Which means compareTo takes an Object, and you should change your overriding method accordingly.
But this raises a new question: how does my 1.4
compiler know anything about generics? It doesn't and it can't. As the compiler is telling you, those interfaces expect Object. Think about it, you want to implement one interface which declares a method argument type of Object, in several classes, each with a different type. Obviously all of those are not valid overrides.

Publish to folder but website says: 'Not Found: Resource does not exist'

Hi Everyone,
I'm new here so I apologise sincerely if a similar question has been asked and answered.
Well, I am currently trying to make a webpage for my mom on iWeb 08 and we also purchased a personal domain name. We are really new to this so I suppose its all still a bit confusing..
I figured out we needed to enter a 'CNAME' into the domain site in order for our iWeb pages to get redirected to her site. And so we put in 'web.me.com' (I think) and were told that it 'should' work. So when I went to her personal URL, it initially asked for a username and password (even though I did not set one up through iWeb). I typed in her personal username and password as this was the only plausible one I could think of... but then the page loaded and the only thing it says is "Not Found: Resource does not exist."
I'm not sure what is wrong - did I input the wrong CNAME or was I supposed to do something else as well as "Publish to a folder" --> then enter the URL for the site at bottom...?
Would really appreciate some feedback - so lost right now!!

Why are you publishing to a folder? You only need to do this if you are uploading directly to the domain webspace and you need an ftp client to do this such as Cyberduck.
CNAME is only used if you are publishing the site to a MobileMe account and you are forwarding the domain to your MMe account?
What is it that you are doing?
If using CNAME, then you need to go to your MMe account and enter the domain name under the personal section, enter personal domain. Then publish your site and then go to your domain name registrar and go to the DNS settings and set the CNAME up to forward to web.me.com.
If you are using CNAME forwarding, then from within iWeb you need to click on Publish All to MobileMe and NOT TO A FOLDER. The folder option is ONLY if you are uploading directly with ftp to your domain space.

UPC_F104 Entry not possible, var does not have replacement type user-spec.

Hi,
On of my exit variable keeps issuing me the following message when selecting a value:
UPC_F104 Entry not possible, var does not have replacement type user-spec. vals
This exit variable is based on other variables (non-user specific). The indicator 'Restriction of values required by user' is flagged.
Any idea what might be the issue ?
Thanks
David

David,
User exit variables won't work if there are multiple rows of values being derived incase 'Restriction of values required by user' is flagged.
Make sure that derivation of variable value is restricted to only one row.
if you have a need to derive multiple rows of values, simply uncheck the flag 'Restriction of values required by user' & you will be good to go.
hope it helps.

is not abstract and does not override abstract method actionPerformed
Oh, I see that the title of your post is an error message? Ok. Well, the test class is declared as implementing an ActionListener. That means the test class must have an actionPerformed() method. Your test class apparently does not.
It does not appear that the test class needs to implement ActionListener. You are using annonymous classes as listeners.

Is not abstract and does not override abstract method tablechanged

I will remove all the gui code to make it shorter, but my problem lies with my InteractiveTableModelListener.
public class Meet extends JPanel{
private static void createAndShowGUI() {
        JFrame frame = new JFrame("MEET_dataTable");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new Meet(), BorderLayout.CENTER);
        frame.pack();
        frame.setVisible(true);
public class InteractiveTableModelListener implements TableModelListener {
     public void TableChanged(TableModelEvent evt) {
if (evt.getType() == TableModelEvent.UPDATE) {
      int column = evt.getColumn();
      int row = evt.getFirstRow();
      dataTable.setColumnSelectionInterval(column + 1, column + 1);
      dataTable.setRowSelectionInterval(row, row);
class InteractiveRenderer extends DefaultTableCellRenderer {
protected int interactiveColumn;
public InteractiveRenderer(int interactiveColumn) {
      this.interactiveColumn = interactiveColumn;
public Component getTableCellRendererComponent(JTable dataTable,
     Object value, boolean isSelected, boolean hasFocus, int row,
     int column)
Component c = super.getTableCellRendererComponent(dataTable, value, isSelected, hasFocus, row, column);
   if (column == interactiveColumn && hasFocus) {
     if ((Meet.this.tableModel.getRowCount() - 1) == row &&
        !Meet.this.tableModel.hasEmptyRow())
         Meet.this.tableModel.addEmptyRow();
    highlightLastRow(row);
return c;
public void highlightLastRow(int row) {
     int lastrow = tableModel.getRowCount();
if (row == lastrow - 1) {
      dataTable.setRowSelectionInterval(lastrow - 1, lastrow - 1);
else {
      dataTable.setRowSelectionInterval(row + 1, row + 1);
     dataTable.setColumnSelectionInterval(0, 0);
public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
            UIManager.put("swing.boldMetal", Boolean.FALSE);
            createAndShowGUI();
}As i say, i have removed all the gui code to make it shorter, but in this code i create the table and add all the model to it. I am being returned with the error
Meet.InteractiveTableModelListener is not abstract and does not override abstract method tableChanged(javax.swing.event.TableModelEvent)in javax.swing.event.TableModelListener
what would be causing this error?
Cheers

Sorry, just figured out my silly error, the method is tableChanged not TableChanged.
cheers

Is not abstract and does not override abstract method ERROR

Hello. I'm new at all this, and am attempting to recreate a sample code out of my book (Teach Yourself XML in 24 Hours), and I keep getting an error. I appriciate any help.
This is the Error that I get:
DocumentPrinter is not abstract and does not override abstract method skippedEntity(java.lang.String) in org.xml.sax.ContentHandler
public class DocumentPrinter implements ContentHandler, ErrorHandler
        ^This is the sourcecode:
import org.xml.sax.Attributes;
import org.xml.sax.ContentHandler;
import org.xml.sax.ErrorHandler;
import org.xml.sax.Locator;
import org.xml.sax.SAXParseException;

public class DocumentPrinter implements ContentHandler, ErrorHandler
// A Constant containing the name of the SAX parser to use.
private static final String PARSER_NAME = "org.apache.xerces.parsers.SAXParser";
public static void main(String[] args)
   // Check to see whether the user supplied any command line arguments. If not, print an error and exit.
   if (args.length == 0)
     System.out.println("No XML document path specified.");
     System.exit(1);
   // Create a new instance of the DocumentPrinter class.
   DocumentPrinter dp = new DocumentPrinter();
   try
     // Create a new instance of the XML Parser.
     XMLReader parser = (XMLReader)Class.forName(PARSER_NAME).newInstance();
     // Set the parser's content handler
    // parser.setContentHandler(dp);
     // Set the parsers error handler
     parser.setErrorHandler(dp);
     // Parse the file named in the argument
     parser.parse(args[0]);
   catch (Exception ex)
     System.out.println(ex.getMessage());
     ex.printStackTrace();
public void characters(char[] ch, int start, int length)
   String chars ="";
   for (int i = start; i < start + length; i++)
     chars = chars + ch;
System.out.println("Recieved characters: " + chars);
public void startDocument()
System.out.println("Start Document.");
public void endDocument()
System.out.println("End of Document.");
public void startElement(String namespaceURI, String localName, String qName, Attributes atts)
System.out.println("Start element: " + localName);
for (int i = 0; i < atts.getLength(); i++)
System.out.println(" Attribute: " + atts.getLocalName(i));
System.out.println(" Value: " + atts.getValue(i));
public void endElement(String namespaceURI, String localName, String qName)
System.out.println("End of element: " + localName);

System.out.println("Recieved whitespace.");

System.out.println("Recieved processing instruction:");
System.out.println("Target: " + target);
System.out.println("Data: " + data);
public void setDocumentLocation(Locator locator)
// Nada
public void error(SAXParseException exception)
System.out.println("Parsing error on line " + exception.getLineNumber());
public void fatalError(SAXParseException exception)
System.out.println("Fatal parsing error on line " + exception.getLineNumber());
public void warning(SAXParseException exception)
System.out.println("Warning on line " + exception.getLineNumber());

Check to make sure that the arguments are consistent with your ContentHandler class. Probably the wrong type.
I think you forgot to include the skippedEntity method, it seems to be missing. Even if an implemented class has a method that you are not using, you still have to include the method in your code even if it doesn't do anything.
