------------------------+---------------------------------------------------
 When using the AjaxViewer and trying to clear a selection then this
 selection is not cleared server-side.
 This is related to MGOS 2.6 and the preview release of MGOS 3.0.

 Steps to reproduce the Problem:

 1. Preview an existing MapDefinition with Maestro[[BR]]
 2. Select a feature[[BR]]
 3. Deselect the feature via toolbar or context menu[[BR]]
 4. Go to the "MapAgent Test Pages"[[BR]]
 5. Under "Rendering" service perform a "MAPIMAGE"-Request of the area
 where you formerly selected the feature.[[BR]]
 6. The selection is rendering with the map Image.[[BR]]

 I turned on the browsers network analysis and detected a "silent" error
 when you are deselecting features.
 The request that should probably clear the selection returns a 559 http-
 error:
