Pretty sure the open file dialog being read only is a feature and not a bug - you also can't move things around, delete things, etc. I actually like this b/c when I want to find a file, I don't want to move something accidentally. It also lets them implement things like dragging a file from Finder to open dialog to select it (that feature doesn't make sense if your file pickers can also modify the files).
