Hi Guido,
As much as i know the Validation, WO checks the NULL value before my code.
the code usually looks like this:
-------------------------------------------
public void validateForSave( ) throws ValidationException
{
super.validateForSave(); // throw an exception if null.
...... my code.
}
-------------------------------------------
i.e. first WO checks and throws an exception and THEN comes my code, which
is defiantly a bit late.
Maybe i don't know what you mean. if you focus me on the point, it would be
great.
Regards,
Sako.
