After putting ids on all the elements in the tables (including
<h:column>, <h:outputText> and <h:outputLink> elements) the problem
seems to have gone away.
I think the element it was choking on was a link that was outside any
forms. So only parent it would have had was the <f:view> element. That
should be okay right? JSF elements don't all have to be within <h:form>
elements do they?

The thing with the duplicate id's is only one possible reason.
you should look at the component path that is indicated - according to
that, your component would need to be a top-level object - it does not
have any parent object at all?

Ok, a bit of an update. The issue only comes up when I have both
of the
tables on the same page. If I comment one out with <%-- %> tags then
everything works fine when adding. I can comment out either one
so it's
not a problem specific to just one of the tables, it's something about
having them both that is causing the problem.
Any ideas?
Thanks again,
