Issue #6572 has been updated by Daniel Crawl.

Status changed from New to Resolved

I've fixed MatlabExpression.xml in svn. If you still get this error when opening the workflow from the demos folder in the actor library, then you'll need to remove $HOME/KeplerData/workflows/module/outreach/demos/Matlab/MatlabExpression.xml.

Bug #6572: An error is thrown when opening MatlabExpression.xml in common/workflows/demos/Matlab in trunk.
https://projects.ecoinformatics.org/ecoinfo/issues/6572#change-21875

* Author: jianwu jianwu
* Status: Resolved
* 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.
