sending to two destinations by label wont work... in this case....why?

Hi, a colleague had this problem and i replicate it on a small model.

i send a message to a queue to create a flowitem and set a label on it named "port" with a value 1 or 2 set as the 3rd parameter on the message. the item goes to another queue wich chooses the destination by the value of the label "port" on the item.

this doesn't work... it always sends the item through the 1st port. only if i create more that one item, the 2nd and on will be sent to port set by the label.

i found that if i put a processor with time 0 between the queues the destination works as intended.. i think it might have to do with the order of the events, but i wanted some clarification on why this does not work...

regards

Queues release flowitems as soon as they are received - there's no delay at all so both queues' sendtoports are evaluated at the time you create the item. Just use stop and resume output before and after you create the part and it will work.
