Right, but I was hoping that perhaps it should do this conversion itself. Here's why. It doesn't make sense for my DAO to be talking about ids in string format, for that would be "out of character," catering to the view. There isn't a way (that I know of) to get the form to populate itself with an array of primitive or lang integers. So therefore, I am asking, do I have to make my DAO bend over backwards to fix this hole in the view? And why can't copyProperties handle this conversion? Seems simple to me.
