Well considering I've wasted about 6 hours trying to figure this out

in the validator for the upload, "value" is the UploadFile, and so call
getSize() on it.

I'd rather configure it once and query for it at runtime.

This is all on the server.

Yes. It turns out I can map a <h:message> (or hopefully
<webuijsf:message>) to the upload to render the error. Previously I was
trying to trap it in my validator and bind an alert's "detail" to a
getter which returned my own message. But now I don't even need my own
message.
Thanx to Deep for his help with this.
