Telerik.Web.UI.RadDockZone can contain only controls of type Telerik.Web.UI.RadDock

I just placed a Prometheus Ajax Manager onto a master page and set a couple of controls and am now receiving this error.  I can't seem to figure out why.  Does anyone have any clues on what to look for with this error.  I didn't receive this error prior to placing the new ajax manager on the master page so I'm pretty much at a loss on it.

I did some more testing on this and found that I had the ajaxmanager set to update a raddock with the original Radcontrols ajaxmanager.  When I switched to the prometheus ajaxmanager, that is when I got the error.  I then moved from the raddock as the updateable control to the radpanel that was inside the raddock with the prometheus ajaxmanager.  No I don't get any updates on the radpanel.

What is going on with this and how do I fix it?  It is becoming very critical and there don't appear to be any solutions online...
