<h1><a href="https://projects.ecoinformatics.org/ecoinfo/issues/6233">Bug #6233: DirectoryListing NPE </a></h1>
<ul>
<li>Author: Daniel Crawl</li>
<li>Status: New</li>
<li>Priority: Normal</li>
<li>Assignee: Derik Barseghian</li>
<li>Category: actors</li>
<li>Target version: 2.5.0</li>
<li>Bugzilla-Id: </li>
</ul>
<p>The DirectoryListing actor has an NPE:</p>
<p>java.lang.NullPointerException<br /> at ptolemy.util.RecursiveFileFilter.accept(RecursiveFileFilter.java:141)<br /> at java.io.File.list(File.java:1027)<br /> at ptolemy.util.RecursiveFileFilter.listFiles(RecursiveFileFilter.java:252)<br /> at ptolemy.actor.lib.io.DirectoryListing.fire(DirectoryListing.java:270)<br /> at ptolemy.actor.AtomicActor.iterate(AtomicActor.java:465)</p>
<p>I'm attaching an example model that demonstrates the problem in Vergil.</p>
