Question: Maple T.A. system error when student logs into assignment

Hello - thanks rcoe for your previous post. One of my students encountered a system error after clicking the link to his assignment and entering his username and password. I created a "fake student" and was able to recreate the error a couple times after randomly opening and closing some assignments. The error stopped occuring after I logged in as the instructor and cleared any active assignments the student had. I am running Maple TA version 2.0.1. Is this a bug or do you have any suggestions on how to avoid this error in the future? Here are the two error messages I received (at different times): java.lang.NullPointerException at proctoredTest.Login.run(Login.java:288) at server.resources.JavaCGIResource.writeTo(JavaCGIResource.java:143) at server.Httpd.handleRequest(Httpd.java:238) at server.Httpd.run(Httpd.java:201) java.lang.NullPointerException at gateway.PageManager.(PageManager.java:35) at gateway.PageManager.getPageManager(PageManager.java:29) at proctoredTest.QuestionSheet.run(QuestionSheet.java:197) at server.resources.JavaCGIResource.writeTo(JavaCGIResource.java:143) at server.Httpd.handleRequest(Httpd.java:238) at server.Httpd.run(Httpd.java:201) Thanks, Marc
