I have got a button with four drop-down radio commands which shares a =
single state. The state is however never saved.

Tracing into the source and find that =
RadioState.RadioStateManager#registerState(String, RadioState) does the =
followings:

1. check the map
2. create a radio group if not found
3. put the state to be saved into the group

but it does NOT add the group to the hashmap!!!

Could this be a bug?

Thanks

Hei

I guess you are probably missing the command state parameter in the
contribution. Check these links on how to contribute a radio state button:
