Hello,<br><br>I'm a beginner with Kepler 2.0 and Im trying to execute a simple workflow which uses a WSWithComplexTypes Actor and SDF Director. I think I did everything right, however when i execute this workflow I get the next error:<br>
<br>----------------------------------------------------------------------------------------------------------------------------------<br>ptolemy.actor.sched.NotSchedulableException: Actors remain that cannot be scheduled!<br>
<br>Note that there are many reasons why a graph cannot be scheduled:<br>* SDF Graphs with feedback loops should have an actor with a delay in the loop, such as a SampleDelay.* The SDF director has an "allowDisconnectedGraphs"parameter, which, when true, permits disconnected SDF graphs.<br>
* The token consumption rate and production rates might be mismatched.  Usually, actors produce one token or consume one token on a port.  To produce or consume multiple tokens per firing, add a "tokenConsumptionRate" or "tokenConsumptionRate" parameter to the appropriate port.<br>
For details, see the SDF chapter in Volume Three of the Ptolemy II design doc at <a href="http://ptolemy.eecs.berkeley.edu/ptolemyII/designdoc.htm">http://ptolemy.eecs.berkeley.edu/ptolemyII/designdoc.htm</a><br>Unscheduled actors:<br>

<br>I've attached the workflow xml file because it's big to write it here.<br><br>Could anyone help me ?<br><br>Thanks in advance.<br><br>Best,<br>Hector<br>
