Description

I would only report this bug with knowledge that an inconsistency exists in the
BeanUtils converters. When using the converter IntegerArrayConverter, the
converter attempts to parse a String[] to an int[], however it makes no attempt
to do the far easier conversion from int[] to String[] in StringArrayConverter.
This happens to be a very important conversion since multiple select boxes in
html forms must be set at a string array even though the model often transfers
data to the form as an int[]. The two conversions are equally important and it
is, in my mind, a missing feature that the conversion exists in one case and not
in the other. The follow is the necessary patch to add this convertor.

As you can see, the added functionality is copied almost directly from
IntegerArrayConverter.
