First of all thanks for answering my question.

Ok added some stack dumps to my code:

First before I call the save changes that calls the validation code:

             try{
                 logger.debug("Stack dump 1 - ");
                 Thread.dumpStack();
                 ec.saveChanges();
			}catch(Exception e){
                 logger.debug(e);
                 s.setErrorMessage(e.getMessage());
                 ec.revert();
                 return null;
             }

Then I added some code to produce stack dump in the validation code:

	public String validateHPostal(String value) throws  
NSValidation.ValidationException {

         logger.debug("Stack dump 2 - ");
         Thread.dumpStack();

         logger.debug("Value - " + value);

         String str = value;

         logger.debug("String - " + str);

         if (str == null || str.length() == 0 ){
             logger.debug("Value is null so we are throwing exception");
             logger.debug(value);
			throw new NSValidation.ValidationException("PostalCode cannot be  
left blank.");
		}else if( Pattern.matches("[A-Z][0-9][A-Z][0-9][A-Z][0-9]",  
str.subSequence(0, str.length()))){
             logger.debug("The string matches a Canadian postal code");
             return str = str.substring(0,3) + " " + str.substring(3,6);
         }else if(Pattern.matches("[A-Z][0-9][A-Z] [0-9][A-Z][0-9]",  
str.subSequence(0, str.length())) || Pattern.matches("[0-9]{5}(-[0-9] 
{4})?", str.subSequence(0, str.length()))){
             logger.debug("The string is a Postal Code or Zip Code");
             return str;
         }else{
             logger.debug("Stack dump 3 - ");
             Thread.dumpStack();
             logger.debug("We are throwing an exception because the  
registrant did not provide a valid Canadian postal code");
             throw new NSValidation.ValidationException("You must  
provide a valid Canadian postal code or American zip code");
         }
	}

Here is the log output:

I guess I should give you more information....The class that this  
validation method exist is in called Registrant and can have a  
relationship with another EO object called Guest.   In this case  
firstName and lastName come from the Guest object.  The problem is I  
have checked my model (and even the database table) and firstName and  
lastName in the Guest class are allowed to be null.  I am not sure  
why it is throwing exceptions for the firstName and lastName.  The  
Registrant EO object does not require a relationship to a Guest  
object.  In this case I am not even creating a Guest object.  Again  
thanks for you help.

Regards,
Jeff
