----------------------------------------
This workflow (see attachment) has two parameters. The first one, called 
datadir, is Parameter type and the second one, called outputdir, is 
StringParameter type. The second one use the first one's as part of its value: 
$datadir/output. When I copy and paste parameter outputdir on the canvas, no 
error dialog pop up. But the console has an exception messages.

ptolemy.kernel.util.IllegalActionException: Warning:, there was a problem 
propagating "outputdir".
