[rules-users] Updating a user defined error object using drools

[Wolfgang Laun]

You would write rules for checking the fields of Employes, e.g.,

rule "must have department"
when
   $e: Employee( department == null )
then
   Errors e = new Errors();
   e.setFieldName( "department" );
   e.setMessage( "missing value" );
   e.setEmployee( $e );
   insert( e );
end

You might not have to insert e. You might want to retract the Employee fact.
