Direct navigation to a trait value history generates the attached exception.  The navigation actually seems to work but for some reason also generates the error message.


Steps to Reproduce:
1. Navigate to a Inventory->Monitoring->Traits and then dbl-click on a a trait.
2. Capture the url, it should have an anchor like:

  #Resource/RESOURCEID/Monitoring/Traits/TRAITID

3. Navigate to Reports or something outside of the current resource detail 
4. Drop the captured url in the browser and hit return
  
Generates the attached exception.
