Extending/External custom fields

Hello all
Is there anybody out this has implemented “Extending/External custom fields” to connect to an external database and create a dynamic list?

If so are you willing to share your example and or code?

I have been trying to use the RT 4 Doc and example but just can’t get it to work.

Thanks for your help
