KeyError: if the type is in another module.

[CoderHuo]

ASN.1 module:

IMPORTS
    SLPAddress, QoP, PosMethod  FROM ULP-Components
    Ver2-SUPL-INIT-extension    FROM ULP-Version-2-message-extensions
    Ver2-Notification-extension FROM ULP-Version-2-parameter-extensions
    Ver3-SUPL-INIT-extension    FROM ULP-Version-3-message-extensions;

Notification ::= SEQUENCE {
  notificationType  NotificationType,
  encodingType      EncodingType OPTIONAL,
  requestorId       OCTET STRING(SIZE (1..maxReqLength)) OPTIONAL,
  requestorIdType   FormatIndicator OPTIONAL,
  clientName        OCTET STRING(SIZE (1..maxClientLength)) OPTIONAL,
  clientNameType    FormatIndicator OPTIONAL,
  ...,
  ver2-Notification-extension   Ver2-Notification-extension OPTIONAL}

ULP-Version-2-parameter-extensions defines the Ver2-Notification-extension define type.

Debug:

    return module.resolve_type_decl(module.user_types()[type_decl.type_name], referenced_modules)
KeyError: 'Ver2-Notification-extension'

(edit: formatted the code sample and removed some accidental styling /kimgr)

There are (at least) two problems here:

• asn1ate does not currently handle imports very well, the mapping from ASN.1 imports to Python imports is not entirely trivial
• Even if it did, you would still need the contents of ULP-Version-3-parameter-extensions available to asn1ate, so it can look up types like Ver2-Notification-extension from it. The easiest way to make that happen is usually to concat all the modules into a single file.

But even so, there are problems with asn1ate and multi-modules, see existing issues #44 and #59.
