[mapguide-users] Mapguide beta 2.4: AjaxViewer SetSelectionXML() seems not working

MapGuideSample.zip Hi all,

I'm testing beta 2.4 and I'm experimenting an error on AjaxViewer
SetSelectionXML(). If I execute, nothing is selected.

I've built a very simple task pane I have set as initial URL in my basic
WebLayout.

If I follow with debugger, I can see that selection.ToXml() seems working
properly.
But as a result of executing Java Script, I get ther right zoom to the right
region, but nothing is selected.

The same code for Mapguide 2.2 woked properly.

Anybody have any idea if something is changed?...

Best regards
