Bug #6572

closed

An error is thrown when opening MatlabExpression.xml in common/workflows/demos/Matlab in trunk.

Description

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.
