Question on customizing OAAttrValException

Question

I have validations coded in EO's validateEntity().
They are working properly with my custom exceptions message.
Validation Code in EO:
    if (getObjectCode().length() < 4)
      MessageToken[] ObjectCodetokens = { new MessageToken("DIGIT", "4") };
      throw new OAAttrValException (
            OAException.TYP_ENTITY_OBJECT,
            getEntityDef().getFullName(), // EO name
            getPrimaryKey(), // EO PK
            "ObjectCode", //attribute name
            getObjectCode(), // bad attribute value
            "XX", //message application short name
            "XX_FWK_DIGIT_REQUIRED",
            ObjectCodetokens); // message name
    }The exception shows like the following on top of the page, if object code input is less then 4 digit
Row 1 ObjectCode - 4 digit numeric required.My question is, is there a way to get rid of "Row 1 ObjectCode -" and just show "4 digit numeric required."?
(Note: "Row 1 ObjectCode -" is not part of my custom exception message.)
Thanks.

You can customize the "Row 1" etc text. You do this by using the view property ROW_DISPLAY_PREFIX_ATTR_NAME. You set the value to name of a transient view attribute. Then, in your VORowImpl, you build the string that will be displayed instead of "Row 1". For example if your view attribute is called ErrorText you would have this:
public String getErrorText{}
return "Error for " + this.getAnotherAttibuteValue() + ":";
}ROW_DISPLAY_PREFIX_ATTR_NAME is documented in the OAF Developer's Guide.
