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.
The complete error message follows, my apologies for
not including it originally.
