This error and several related ones that appear when showing the 'tree' view for a dataset's files all appear to come from the way Primefaces implements a tree. I don't see any ways to fix them w/o changing the primefaces code. As with a couple other things, I think that is doable, but I'm not sure it is worth the effort versus reporting the problem and waiting. (I did look through their source code a bit on this and see that there is a v11RC2 out that has some changes already - if we do want to make PF code changes (or report new bugs), we should probably wait until v11 is out and we've upgraded to that.)
