Description

If I try to change the version of a dataflow from Version 1 to Version 2, and the changes result in a connection being removed or its destination changing, all is OK If the destination is not an Output Port. However if the destination of the connection in the current version is an Output Port, and the Output Port is running, the connection will not be updated. The logs will show no errors, and the UI will either indicate that the connection couldn't be updated because the destination is running, or it will claim that the update was successful (depending on the situation). But in either case, the flow will not have been updated properly.
