<h1><a href="https://projects.ecoinformatics.org/ecoinfo/issues/6413">Bug #6413: error when switching to DDF inside Case refinement</a></h1>
<ul>
<li>Author: Daniel Crawl</li>
<li>Status: New</li>
<li>Priority: Normal</li>

<p>I get an exception when switching from SDF to DDF inside a Case Refinement. It seems to be caused by having an unconnected input port.</p>
<p>To reproduce:</p>
<p>1. open $PTII/ptolemy/actor/lib/hoc/test/auto/Case1.xml<br />2. add a new input port to Case<br />3. run the model<br />4. open the Case actor and replace SDF in each Refinement with DDF<br />5. run the model</p>
<p>The error is:</p>
<p>java.lang.IllegalArgumentException: hasToken() requires a positive argument.<br /> at ptolemy.actor.Mailbox.hasToken(Mailbox.java:149)<br /> at ptolemy.actor.IOPort.hasToken(IOPort.java:2061)<br /> at ptolemy.domains.ddf.kernel.DDFDirector.prefire(DDFDirector.java:649)<br /> at ptolemy.actor.CompositeActor.prefire(CompositeActor.java:1665)<br /> at ptolemy.actor.lib.hoc.CaseDirector.prefire(CaseDirector.java:267)<br /> at ptolemy.actor.CompositeActor.prefire(CompositeActor.java:1665)<br /> at ptolemy.actor.CompositeActor.iterate(CompositeActor.java:1082)<br /> at ptolemy.actor.sched.StaticSchedulingDirector.fire(StaticSchedulingDirector.java:211)<br /> at ptolemy.domains.sdf.kernel.SDFDirector.fire(SDFDirector.java:492)<br /> at ptolemy.actor.CompositeActor.fire(CompositeActor.java:450)<br /> at ptolemy.actor.Manager.iterate(Manager.java:787)<br /> at ptolemy.actor.Manager.execute(Manager.java:352)<br /> at ptolemy.actor.Manager.run(
