The service name should be prefixed with the platform name. The constant that holds the service name should start with SERVICE_.

This doesn't seem to be used and is not needed. The instance can access the attribute directly.

If I delete methods source_list and source, then select source option is not showing up in web ui.

Don't remove those. Comments in reviews are directed at the line at the end of the code box shown. In this case that's line 181. So I was only referring to the cmode property.

Nothing is checking this return value. It also makes the return value inconsistent since the call is done inside a check. Just remove the return.

This should be made part of the service validation schema. Make a custom validator that checks that the passed cmode is in the cmode list set.

Caveat is that the service schema cannot be defined as a constant at the module level anymore but has to be moved inside the setup platform function to allow access to the imported CMODE_LIST_SET.
