NullPointerException in JBoss Tools Freemarker IDE

I've sent this to the JBoss Tools list as well, with no responses. I thought someone on this list might use the JBoss Freemarker editor and have an idea of how to resolve the problem:

I have a couple of files that consistently cause the Freemarker IDE in JBoss Tools to throw a NPE. All my other files are fine. The error occurs when I type a "${" prefix to a variable. The error message is:

 Problems occurred when invoking code from plug-in: "org.eclipse.jface".



The stack trace is:
