I forgot to mention it, but I can't use org.apache.struts.util.LabelValueBean, unfortunately, as I am using an older version of Struts. Though it would be nice to upgrade, my supervisor has told me that I have to use the older version as the server is set up to run it and there are other apps on the server that require it. Or something. It was one of those, "Because I said so," situations, so there's really nothing I can do with respect to that.
I'm fooling around with some of the other things you mentioned, but I've never heard of optionsCollection before now. I think it is 1.1 as well though, yes? I'm stuck with 1.0.2 solutions.
