False warning messages from .NET OPC UA client session

[milankase]

The method ProcessPublishResponse of the client session (Opc.Ua.Client.Session) probably generates false warning messages Sequence number={0} was not received in the available sequence numbers. The code that checks for the sequence numbers does not take into account the subscription id. If there is more than one subscription in the session then this code mixes up the sequence numbers from different sessions and issues the above mentioned message.

The code responsible:

foreach (var acknowledgement in acknowledgementsToSend)
{
    if (!availableSequenceNumbers.Contains(acknowledgement.SequenceNumber))
    {
        Utils.Trace("Sequence number={0} was not received in the available sequence numbers.", acknowledgement.SequenceNumber);
    }
}

Suggested fix:

    ...
    if (acknowledgement.SubscriptionId == subscriptionId && !availableSequenceNumbers.Contains(acknowledgement.SequenceNumber))
    {
    ...

Can anybody confirm?
