I have WCS with location installed. From the Cisco documentation the WCS with location is suppose to provide a small set of location/mapping functions. Adding the location appliance will give you historical data.
When trying to view clients on the floor map it says that "No clients found on this floor. Either you dont have any location server which locates clients or no clients are detected."
There are several clients that are online and show up in the other search function but they arent mapped out.
I'm having a similar problem with WCS not displaying my client(s) on the Heatmap. I have setup a lab environment with a single 2006 controller and 2 1010 APs. I walked around the perimeter of my office space to verify roaming between controllers but WCS still doesn't display my client. When I try to reload the heatmap it says:
Loaded 0 out of 0 Clients.
I have also verified that Clients are not being filtered from the view.
