Hi,

I'm trying to add a user to an existing assignment via the Edit Assignment page (AssignmentProperties.aspx). I do this by checking the required username and selecting OK.

However when I do this I get the following error in the event log:

SharePoint Learning Kit Error

System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
   at System.ThrowHelper.ThrowKeyNotFoundException()
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at Microsoft.SharePointLearningKit.SlkMemberships.get_Item(Int64 key)
   at Microsoft.SharePointLearningKit.ApplicationPages.AssignmentPropertiesPage.SetMembersList(SlkUserCollection slkUserCollection, CustomCheckBoxList customChkBoxList)
   at Microsoft.SharePointLearningKit.ApplicationPages.AssignmentPropertiesPage.CreateAssignmentPropertiesObject()
   at Microsoft.SharePointLearningKit.ApplicationPages.AssignmentPropertiesPage.SubmitAssignment(Object sender, EventArgs e)

Any ideas?

I'm using SLK 1.6b under SharePoint 2010.

Thanks.
