[Geoprisma-dev] Highlight on shortcut

[Alexandre Dube]

Hey,

  Thanks for the new feature and your hard work.

  I think there might be a small issue on the way it's done.  See at :

http://www.geoprisma.org/samples/shortcut/activateresources/index.php

  * from the first combobox, select 111.  The road gets highlighted.
  * click on map, the road is unhighlighted.
  * from the first combobox, select 113.
  * from the first combobox, select 111.  The road doesn't get highlighted.
  * from the first combobox, select 138.
  * from the first combobox, select 111.  The road gets highlighted.

  Weird.  I guess it's a map "move" event problem...
