I suspect that the cause of the problem is that the Sheboygan sample layer uses a 1.0.0 layer definition and your own layer uses a 1.1.0 layer definition. The SizeContext element was added to the StrokeType element in the later version of the schema, thus if you want to use the Theme code with a newer layer, you'll need to update the style template (arearuletemplate.xml) to include the extra setting.
BTW - SizeContext can be set to either DeviceUnits or MappingUnits. If set to DeviceUnits, the line width is interpreted in the units of your screen, and remains constant regardless of the map scale. If set to MappingUnits, it is interpreted as a real-world size, and thus will increase in width on the screen as you zoom in. Chris.

Now, I have the possibility to select the point layers. I changed also the different reference to the <AreaRule> by <PointRule>. I do not know if these changes are correct because I have a problem with this function (polygon layers), see http://lists.osgeo.org/pipermail/mapguide-users/2009-January/016202.html Regards, Arnaud De Groof ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Chris Claydon Sent: vendredi 9 janvier 2009 19:53 To: MapGuide Users Mail List Subject: [mapguide-users] RE: Theme layer application - point feature layers The sample code generates <AreaRule> elements in a layer definition, and therefore applies only to polygon styles. It should be relatively easy to modify it to handle point layers and styles instead.

The code sample (phpviewersample/theme) allows only selecting the polygon feature layers.
