<h1><a href="https://projects.ecoinformatics.org/ecoinfo/issues/6572">Bug #6572: An error is thrown when opening MatlabExpression.xml in common/workflows/demos/Matlab in trunk.</a></h1>
<ul>
<li>Author: jianwu jianwu</li>
<li>Status: New</li>
<li>Priority: Normal</li>
<li>Assignee: Daniel Crawl</li>
<li>Category: actors</li>
<li>Target version: 2.5.0</li>
<li>Bugzilla-Id: </li>
</ul>
<p>I got the following errors. The main reason is that $name is in the documentation of the actor explaining the expression parameter. If I edit the xml changing from $name to be $$name, the workflow can be opened correctly.</p>
<p>The same workflow works fine with Kepler 2.4. Not sure which changes in Kepler trunk cause this problem.</p>
