Demand Duration Chart Hourglass just keeps spinning

Demand Duration Hourglass just keeps spinning.  You have checked to make sure in both Periscope and Niagara that this is a valid history point.  But the Viewlet does not work.

It turns out that this occurs due to missing facets on the history.  I'm not sure if older AX version (like your JACE) fail to add the facets or if it's something else.  The workaround is to manually add it for any history you'd like to use in the demand duration viewlet.  To do this:

  1. Navigate to your history in the tree inside of Workbench
  2. Right click on your history and select View > Slot Sheet
  3. Add a new slot by right clicking and selecting "Add Slot"
  4. Set the name to "valueFacets" and the Type to baja : Facets 
  5. Click ok

After you manually add the slot the history should be usable by oBIX and work in the demand duration viewlet.  I will let you know when I hear back from Tridium.
