[mapguide-users] how to set selected feature at client in fusion???

Mon Jun 9 21:49:13 EDT 2008

at server in CreateSelectionXML() ,i add  the following line:
selection.Save(resService, map_name); 

at client i  use the following line to refresh the map：
parent.document.getElementById('Map').widget.aMaps[0].drawMap(); 

then it's OK。

thank's a lot, Paul~:handshake:
