[Building Sakai] Gradebook (the original) problem

[Glenn R. Golden]

Does anyone find this at all familiar, from the good old gradebook,  
circa 2.3?

We have a site with a few GB assignments with some scores.  From the  
instructor's view, it looks odd because the Course Grade has 0 average  
and 0 points, and everyone has 0 and an "F".  Folks have actual point  
values and averages and grades for most of the assignments.  Any  
student trying to see the gradebook gets an internal error, here:

org.sakaiproject.tool.api.ToolException:  
org.apache.jasper.JasperException

org 
.sakaiproject.portal.charon.CharonPortal.forwardTool(CharonPortal.java: 
1602)

caused by: java.lang.NullPointerException
    at  
org 
.sakaiproject 
.tool.gradebook.ui.StudentViewBean.init(StudentViewBean.java:216)


The code in StudentViewBean is:

         // Display course grade if we've been instructed to.
         if (gradebook.isCourseGradeDisplayed()) {
             CourseGradeRecord gradeRecord =  
getGradebookManager().getStudentCourseGradeRecord(gradebook,  
getUserUid());
             if (gradeRecord != null) {
                 courseGrade = gradeRecord.getDisplayGrade();
216>>>          percent = gradeRecord.getSortGrade().doubleValue();
             }
         }

The NPE is from what must be a null return from  
"gradeRecord.getSortGrade()".

I did note from the database view of the GB_GRADABLE_OBJECT_T table  
that there is one assignment that has a "1" value for "REMOVED".

Does this sound familiar to anyone?  I'm wondering what about the data  
is messed up, and how to fix it.

(Ray, Josh, are you still out there?)

Thanks!
