Value as concept attribute not providing a list of concepts for measurement entry event

[JesShirley]

Expected behavior

When creating a cohort definition using a measurement entry event, it is expected that adding the "Value as Concept" attribute would provide a list of concepts to select.

Actual behavior

When I select "Add" for the "Value as Concept" attribute, the select concept window opens with a message that states "Please wait while the Vocabulary Provider initializes..." and a list of concepts is never provided.

In the Chrome error log, I can see that the service called ConceptPicker is being used:

So this uses a mini concept browser to select the list of concepts int he domain to choose. If you see, it is trying to call a server side call, but it's returning a 500 error. I can't tell from your screenshot what the URL was, but, 500 errors should have a log error in your WebAPI logs, you can check to see what it is.

Thank you, @chrisknoll. I'll check the WebAPI logs.
