Serialization of nested group using another nested group fails #188

Closed andreasjakobik closed 3 years ago

andreasjakobik commented 4 years ago

Hello,

in the _3gpp_common_fm.yang file (attached) there is a nested group ThresholdInfoGrp that uses another nested group ThresholdPackGrp. In essense we have the following:

grouping AlarmRecordGrp {

        leaf alarmId {
            type string;
        }

        grouping ThresholdPackGrp {
            leaf thresholdLevel {
                type string;
            }
            leaf thresholdValue {
                type string;
            }
        }

        grouping ThresholdInfoGrp {
            leaf measurementType {
                type string;
            }

            uses ThresholdPackGrp;
        }

        list thresholdInfo {
            uses ThresholdInfoGrp;
        }
    }

It seems the fact the groupings are nested (i.e. grouping inside a grouping) makes the serializatin fail as shown in the stacktrace _3gpp-common-fm.zip

Any idea how to fix?
