We receive the following error when trying to remove an empty part from an exam.  I tried adding a question to the part and then removing it but still receive the same error.  Any ideas/solutions?

org.sakaiproject.portal.api.PortalHandlerException: org.sakaiproject.tool.api.ToolException: javax.servlet.jsp.JspException: Argument Error: One or more parameters are null.
