Edited Issue: object not set to instance ... [11344]

Hi Philip,
 
line 1880 of uc_Manage.ascx.vb: grdUsers.DataSource = GetUserList()
GetUserList() sometimes return Nothing resulting in error.
After I added a check to only execure this line when GetUserList() IsNot Nothing, then I ran into another issue:
 
line 2301 of uc_Manage.ascx.vb: has a reference to ctlRoles.SelectedNode
but sometimes ctlRoles.SelectedNode Is Nothing, resulting in error.
So I added a check in the IF line.
 
So I don't have any errors anymore, but unfortunatly the Search doesn't work for me.
I'm using DNN 5.6.1
