OK.
Could you show your code using instanceof which you said is not working?
Another thing to check (a bit stupid, but there is a chance for it to work). As there is only a handful of possible metadata entry types, for each entry you can try to retrieve its value for each possible type. there is a chance that these calls will return null or throw an error if the entry actual type doesn't match the type you pass to it. Something like the following:
for each (var metadataEntry in metadataEntries) { var val = null; var stringValue = metadataEntry.typedValue.getValue(new VclMetadataStringValue); if (val == null && stringValue != null) { val = stringValue; } var booleanValue = metadataEntry.typedValue.getValue(new VclMetadataBooleanValue); if (val == null && booleanValue != null) { val = booleanValue; } var numberValue = metadataEntry.typedValue.getValue(new VclMetadataNumberValue); if (val == null && numberValue != null) { val = numberValue; } var datetimeValue = metadataEntry.typedValue.getValue(new VclMetadataDateTimeValue); if (val == null && datetimeValue != null) { val = datetimeValue; } if (val != null) { System.log("Metadata key: " + metadataEntry.key + " value: " + val.value); }
}
