Desktop Client: Why do I receive a warning like: Activity has unconnected decision cases

When you have an activity with multiple outputs specified, and there are more output options than there are physical lines exiting the activity, then there is one or more specified outputs that do not have a path to follow. Please check to make sure that you have one line for each output specified on the Outputs page and Normal tab.

There are times when it actually may be desirable to have unconnected output paths. That is why this is a "warning" rather than an "error" statement. Simulation will still run even when warnings are issued.
