restoreTransactions does not return receipts

[GoogleCodeExporter]

I get the expected events, but the receipt is null for both the original and 
the current transaction.

This is testing on iOS 5.0.1, Flex SDK 4.6.0

The receipt is provided with the initial transaction, just not in any restored 
transactions.

I note that capiextension.m->generateXml deliberately blanks the receipt:

    if(t.transactionState == SKPaymentTransactionStatePurchased || t.transactionState){
        NSString* d = [[NSString alloc] initWithData:t.transactionReceipt encoding:NSASCIIStringEncoding];
        [retXML appendFormat:@"<receipt>%@</receipt>",d];
        [d release];
    }else {
        [retXML appendFormat:@"<receipt> </receipt>"];
    }

Sorry, meant to add that this is in the sandbox environment.
