Our installation : slk 1.4 (release SLK_203bdbbcb32c) on Moss 2007 , Windows server 2008 r2.
We used to have slk 1.3 everything worked ok .
We created a new environment and installed 1.4 and copied the databases from the old to the new databases .
Applied the patch of
For some reason the assignmentlist is not showing any results to the learners ( for teachers it works ok ).
In the toolbar on the left side the learner sees all the categories (for example 'To Do', 'Overdue',..) with the correct number of assignments ,
but when clicking on one of them instead of showing the learner all his assignments the user gets the following error :
An error occurred. More information may be available in the server event log.
In the eventviewer we get the following error :
SharePoint Learning Kit Error
System.NullReferenceException: Object reference not set to an instance of an object.
(QueryDefintion querydef, List1 renderedRows, HtmltextWriter hw)
at Microsoft.SharePointLearningKit.ApplicationPages.AlwpQueryResults.Page_Load(Object sender, EventArgs e) .
We forgot to mention but the assignmentlist is only showing 2 columns in the header ( 'assignment' and 'status').
Any help would be appreciated !
