[mapguide-users] Unable to select/highlight objects - MGE 2010 Update 1 & AJAX Viewer

[Praveen Rajendra Babu]

Hi,
 This is happening quite regularly and thought of bringing to the group's notice.
When I leave MGE idle, like overnight and the next day morning when I try to access 
the map, it displays perfectly fine. But when I try to select a feature on the map
it shows "x" feature selected, but the object is not highlighted on the map. Also,
any MGE API operations with the selected non-highlighted object fails.
  To resolve the issue, I re-start BOTH MGE server and WWW services. 
I have recently applied the MGE 2010 Update 1 and can't remember anything like this
prior to the update.
 The server Error.log has the below consistent message:
Error: The requested operation version is invalid.
StackTrace:
  - MgOperationThread.ProcessOperation() line 431 file d:\build\testarossa_nightly\build_35.5\ent\os\server\src\core\OperationThread.cpp
  - MgFeatureServiceHandler.ProcessOperation() line 83 file d:\build\testarossa_nightly\build_35.5\ent\os\server\src\services\feature\FeatureServiceHandler.cpp
  - MgFeatureOperationFactory.GetOperation() line 445 file d:\build\testarossa_nightly\build_35.5\ent\os\server\src\services\feature\FeatureOperationFactory.cpp

Please let me know if you want me to enable more logging detail, if that helps.

System details:
MapGuide Server Version: 2.1.0.3505
MapGuide AJAX Viewer Version: 2.1.0.3505
OS: Windows Server 2003 Standard Edition SP 2
IIS Server : V6.0


Thanks for your time.
