Problem with Edit Object Store functionality in simulator?

I'm using the "Edit Object Store" functionality in the simulator to check various changes. However, when I click "OK" my widget restarts but the values remain the same. This is making it hard for me to debug. Furthermore, if I change the value in the properties.xml file and re-run the app the original value is still used. The only way I seem to be able to get the value to update is to use the "App Settings Editor" and send a new configuration to the simulator, which makes sense for "settings" but not necessarily for properties not assigned to settings per se. Am I missing something?

Furthermore, I'm unsure how the widget will react if I change one of these properties in the future.

For reference, I'm using SDK 1.2.11 on a Mac (with latest Eclipse).

Thanks,
Douglas
