I have another DDC in the wizard that works properly, it shows the correct
value when using the wizard previous button.
It's connected to the "deviceType" property of Device and gets its choices
from an enumeration I have.
add(new DropDownChoice("deviceType",
Arrays.asList(DeviceType.values())));
The only difference I can find between this DDC and the one that doesn't
work is where the choices come from.
The DDC that doesn't work gets its choices from the db (through a
LoadableDetachableModel).
On pressing previous I see (with the help of prints) that the DDC holds the
correct model value, that is the one i chose before, but it just wont disply
it!!
any ideas?
