asn1ct:value/1 bug(s)?

[Anders Nygren]

Hi
In the past, (R12B1 or something like that), I have been able to use
asn1ct:value/1 to generate random data according to an ASN.1 spec.

But it seems to not work anymore in R13B02.

Error 1:
In MAP-MS-DataTypes.asn there is

RAB-Id ::= INTEGER (1..maxNrOfRABs)

maxNrOfRABs INTEGER ::= 255

50> asn1ct:value('MAP-MS-DataTypes-v6','RAB-Id').
{error,
    {{case_clause,
         {1,
          {'Externalvaluereference',736,'MAP-MS-DataTypes-v6',
              maxNrOfRABs}}},
     [{asn1ct_value,c_random,2},
      {asn1ct,value,2},
      {erl_eval,do_apply,5},
      {shell,exprs,6},
      {shell,eval_exprs,6},
      {shell,eval_loop,3}]}}

Error 2:
In some cases it returns ok, but with errors in nested elements of the
result.
51>  asn1ct:value('MAP-MS-DataTypes-v6','InsertSubscriberDataRes').
{ok,{'InsertSubscriberDataRes',
        [{asn1_error,
             {not_found,{'MAP-MS-DataTypes-v6','Ext-TeleserviceCode'}}}],
        [{asn1_error,
             {not_found,
                 {'MAP-MS-DataTypes-v6','Ext-BearerServiceCode'}}}],
        {asn1_error,{not_found,{'MAP-MS-DataTypes-v6','SS-List'}}},
        [1,0,1,1,1,0,1,1,1,0,1,1,1,0,1],
        asn1_EMPTY,
        [1],
        {asn1_error,
            {not_found,{'MAP-MS-DataTypes-v6','ExtensionContainer'}}},
        undefined,
        [1,0,1,1,1,0,1]}}

Error 3?:
Also in MAP-MS-DataTypes.asn

T-BcsmTriggerDetectionPoint ::= ENUMERATED {
	termAttemptAuthorized (12),
	... ,
	tBusy (13),
	tNoAnswer (14)}

52> asn1ct:value('MAP-MS-DataTypes-v6','T-BcsmTriggerDetectionPoint').
{ok,asn1_EMPTY}

Is asn1_EMPTY really a valid value for this type?
