Issue #6572 has been reported by jianwu jianwu.

----------------------------------------
Bug #6572: An error is thrown when opening MatlabExpression.xml in common/workflows/demos/Matlab in trunk.
https://projects.ecoinformatics.org/ecoinfo/issues/6572

* Author: jianwu jianwu
* Status: New
* Priority: Normal
* Assignee: Daniel Crawl
* Category: actors
* Target version: 2.5.0
* Bugzilla-Id: 
----------------------------------------
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.

The same workflow works fine with Kepler 2.4. Not sure which changes in Kepler trunk cause this problem.
