I like your solution, but you are using an IntegerSelectChoice as your model, which won't work for me. I need to set my model to a regular Integer since that's what's being persisted on the backend.

However, you can remove all the generic stuff and it will still work. I just migrated to generics yesterday, so the code does work on 1.3.3. Or you can invest in moving to 1.4-m1. It seems to be working great and using generics is nice. -Doug Michael Mehrle wrote: > > Hi Doug: > > Thanks for that - this might just work :-) One problem I'm running into > is that the version of IChoiceRenderer I am using cannot be > parameterized (it's not generic).
