Not entirely sure what your logic needs to be, but the normal approach would
be to associate your Application object with a pre-existing customer from
the database. So your method would look more like (I have also changed the
code to use commons lang, personal preference :-):
public void setAsText(String text) throws IllegalArgumentException
{
Customer obj;
if (StingUtils.isEmpty(text) || !StingUtils.isNumeric(text))
{
setValue(null);
} else {
obj = customerManager.get(Long.parseLong(text));
setValue(obj);
}
}
