JQuery does the same thing: selectors return arrays of matching elements, but if no elements were found, you receive an empty array instead of null. Anyone who thinks this is a better idea hasn't practically worked with the concept. Failing fast (with an NPE or, in the case above, with a Javascript error regarding 'undefined') saves much more time than silently proceeding with an unexpected result. -- Cédric -- You received this message because you are subscribed to the Google Groups "Java Posse" group.
