MSMQ and COMCOM change in Dynamics NAV 5 SP1 Platform Update 2 release

I used to have this code in a solution sending data to MSMQ:

CREATE(MQBus);
CREATE(CC2);
CREATE(XMLDom);
CC2.AddBusAdapter(MQBus,1);

//MESSAGE('Writes to '+‘Message queue://’+JobSetup.“MSMQ TFP Write Path”);
MQBus.OpenWriteQueue(JobSetup.“MSMQ TFP Write Path”,1,1);
OutMsg := CC2.CreateoutMessage(‘Message queue://’+JobSetup.“MSMQ TFP Write Path”);
OutS := OutMsg.GetStream();

// fill the message and send it
XMLDocOut.save(OutS);
OutMsg.Send(0);

// Send to extra queue
MQBus.OpenWriteQueue(JobSetup.“MSMQ TFP Write Path Extra”,1,1);
OutMsg := CC2.CreateoutMessage(‘Message queue://’+JobSetup.“MSMQ TFP Write Path Extra”);
OutS := OutMsg.GetStream();

// fill the message and send it
XMLDocOut.save(OutS);
OutMsg.Send(0);

But after the update - this code only worked with 2-3 records when running - then Navision got “exhausted” and just stopped. Also if not running on NAS!

It took me this whole day (and lots and lots of testing) to find the problem…The key was that sending data to an extra queue is no longer “allowed” by Navision…! I haven’t tested any further - but this is just if anybody else has this problem after updating!!!
