Phew!
A bit of a slog, trying to understand Wicket and the Wicket Viewer, but
I finally seem to have something that works.
I had to change ConverterForObjectAdapterMemento#convertToString
to work with value-type objects.
Otherwise, the Wicket viewer now seems to support choicesXXX for
properties for value types.
I have not tested this for parameters.
One annoying thing I have not completed is getting the layout sorted
out. The choices dropdown list appears outside the property "label"
range, and renders a bit vertically displaced.
Dan, if you get a chance, could you look at ValueCollections.java/html
and see what is missing?
I've tested this for Date and String, and it works.
Ah - nearly forgot - I also don't (yet) know how to correctly initialise the
drop-down list with the existing property value. It always starts off with
"Choose One", instead of the existing value.

Kevin
