[mapguide-commits] r6703 - branches/2.4/MgDev/Desktop/MapViewer

[svn_mapguide at osgeo.org]

Author: jng

New Revision: 6703

Modified:
   branches/2.4/MgDev/Desktop/MapViewer/MgThemeControlImpl.cs
Log:
mg-desktop: The theme component (like its AJAX and Fusion counterparts) only works against Polygon layers. So filter out non-polygon layers from the list of themeable layers.

Modified: branches/2.4/MgDev/Desktop/MapViewer/MgThemeControlImpl.cs
