Using NSPropertyListSerialization with NSArray of NSDictionaries


It would be very useful for us to store an ordered array of dictionaries using NSPropertyListSerialization. The code below works fine if processingInfo is an NSDictionary, but fails with the message "Property list invalid for format" if processingInfo is an array of dictionaries.

Is there any other reasonable way to do this? The docs say that as long is everything is an array, dictionary, number, string, or date it should work. Should I file a bug?

Thanks for any hints,

Rick

if (processingInfo) {

xmlData = [NSPropertyListSerialization dataFromPropertyList: [processingInfo objectAtIndex:0]
format:NSPropertyListXMLFormat_v1_0
errorDescription:&error];
if (xmlData) {
char *str = malloc([xmlData length]+1); // Add trailing '\0'
memcpy(str,[xmlData bytes],[xmlData length]);
str[[xmlData length]] = '\0';
miattputstr(mincid, varid, "processingInfo", str);
free(str);
} else {
NSLog(error);
[error release];
}
}
