Once the connection is established, an ADMS call request.getDDOList() retrieves the list of AirDDOs. This call is made by app.component which provides it back to ddo-choice.

The list we receive contains for each AirDDO a GUID (used to register for an AirDDO), and a Name (username).

Once the list is populated, each selection change within this list emits a DDOChanged event that is retrieved by app.component. The latter creates the connection to the AirDDO via OAS and then uses the getDDOConfig method to retrieve the configuration of the AirDDO and instantiate the drive components. The default AirDDO is loaded first (see SubscriberDDO, server url).
