Error when playing the sample travel-expense workflow on the JSF app

When trying to play the travel expense workflow on the JSF side, I get an exception:

Caused by: javax.el.ELException: Error reading 'currentSelectPage' on type org.nuxeo.ecm.platform.query.nxql.CoreQueryDocumentPageProvider
at javax.el.BeanELResolver.getValue(BeanELResolver.java:110)

To reproduce, start a workflow from the javascript application, then go to the home dashboard, workflow, and then try to process a task. This is when the error is produced.
