    NullPointerException in Freemarker IDE

    ryounes Newbie

      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:

       

      java.lang.NullPointerException
