Hi Jackie

All i get in MGOS2.4 RC2 is:

Command line output:
(4980) The specified class was not found.

error.log file:
<2012-10-01T11:36:44> 	4980	Ajax Viewer	::1	Administrator
 Error: The specified class was not found.
 StackTrace:
  - MgRenderingServiceHandler.ProcessOperation() line 83 file
c:\mg-2.4-x64\mgdev\server\src\services\rendering\RenderingServiceHandler.cpp
  - MgOpQueryFeatures.Execute() line 125 file
c:\mg-2.4-x64\mgdev\server\src\services\rendering\OpQueryFeatures.cpp
  - MgServerRenderingService.QueryFeatures() line 848 file
c:\mg-2.4-x64\mgdev\server\src\services\rendering\ServerRenderingService.cpp
  - MgServerRenderingService.RenderForSelection() line 1520 file
c:\mg-2.4-x64\mgdev\server\src\services\rendering\ServerRenderingService.cpp
  - MgServerDescribeSchema.GetClassDefinition() line 1061 file
c:\mg-2.4-x64\mgdev\server\src\services\feature\ServerDescribeSchema.cpp	

This is when I try selection on the map. It only happens at a certain zoom
level  so it must be some layer causing problems, but still no info on which
layer.
I will try to delete the layers one by one until the problem is gone to
identify the problematic layer.

Hans...
