[Ada] wrong code generated when 2 properties point to same definition

[michelealbano]

Description

When processing a YML file with a parameters that has two properties that refs to the same "definition (see YML file), the adb file for the model has got a wrong "Deserialize" method, which cannot be compiled. For example, with the YML below, it has a line saying:
Swagger.Streams.Deserialize (Object, "commands", Value.Commands);
that should be a:
Deserialize (Object, "commands", Value.Commands);

Suggest a fix/enhancement

Change how the model body (adb) is generated. In the example at hand, you generate a correct code for the "requestedQoS" property, but a wrong one for the "commands" property. Thus, instead of:

  Deserialize (Object, "requestedQoS", Value.Requested_Qo_S);
  Swagger.Streams.Deserialize (Object, "commands", Value.Commands);

please generate a:
Deserialize (Object, "requestedQoS", Value.Requested_Qo_S);
Deserialize (Object, "commands", Value.Commands);
