Add validation in VORowImpl

Question

Hi,
I'm extending a page to add a validation on a textbox. When importing the PersonDetailsVO of the page, it does not have an Entity object attached. And normally, validations on a particular field are done on EOImpl. Can i extend and add my validation codes in the VORowImpl file itself?
thanks,
vik

Answer 1

Exactly, its based on custom sql. I need to insert a basic validation a textbox National Identity (value must not be greater than 13char).
Ive extended my VO and inserted the following codes in its XX_RO_PersonDetailsVORowImpl:
public class XX_RO_PersonDetailsVORowImpl extends PersonDetailsVORowImpl
protected static final int MAXATTRCONST = oracle.jbo.server.ViewDefImpl.getMaxAttrConst("oracle.apps.per.selfservice.common.server.PersonDetailsVO");;
* This is the default constructor (do not remove)
public XX_RO_PersonDetailsVORowImpl()
//my codes Begin
public void setNationalIdentifier(String s)
{   //EPO065 Add validation on National ID textbox
if (s != null)
// Proper message with the message name should be seeded.
if (s.length() > 13)
{  throw new OAAttrValException(OAException.TYP_VIEW_OBJECT,                                    
getViewObject().getFullName(), // VO name
"NationalIdentifier", // Attribute Name
super.getNationalIdentifier(), // Attribute value
"XXPER", // Message product short name
"XXPER_RO_ER0002"); // Message name
super.setNationalIdentifier(s);
// my codes End
Im getting the following errors when compiling:
Error(34,20): constructor OAAttrValException(int, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String) not found in class oracle.apps.fnd.framework.OAAttrValException
