Solve the problem that information object table with one entry can not be properly handled

E-RABToBeSetupItemBearerSUReqIEs S1AP-PROTOCOL-IES ::= {
    { ID id-E-RABToBeSetupItemBearerSUReq   CRITICALITY reject	TYPE E-RABToBeSetupItemBearerSUReq	PRESENCE mandatory },
    ...
}

result in 'FATAL: Information Object Set E-RABToBeSetupItemBearerSUReqIEs contains no objects at line xxxx'

If it contains more than one entry then there is no problem.

E-RABSetupRequestIEs S1AP-PROTOCOL-IES ::= {
    { ID id-MME-UE-S1AP-ID                  CRITICALITY reject  TYPE MME-UE-S1AP-ID                     PRESENCE mandatory }|
    { ID id-eNB-UE-S1AP-ID                  CRITICALITY reject  TYPE ENB-UE-S1AP-ID                     PRESENCE mandatory }|
    { ID id-uEaggregateMaximumBitrate       CRITICALITY reject  TYPE UEAggregateMaximumBitrate          PRESENCE optional  }|
    { ID id-E-RABToBeSetupListBearerSUReq   CRITICALITY reject  TYPE E-RABToBeSetupListBearerSUReq      PRESENCE mandatory },
    ...
}
