Additionally, I found that when you include a RasterLayerDefinition in the TileSetDefinition, the tiles are no longer white, but a mix of colors.

Seems like a bug to me

Hi,

In our application I use a MapDefinition with an external TileSetDefinition of the type "Default Tile Provider". We access this MapDefinition in our OpenLayers frontend from a map that is set to a local coordinate system (EPSG:25832). In the TileSetDefinition I have defined this CoordinateSystem and the scales in which I want the tiles to be created:

500000,250000,100000,50000,25000,10000,5000,2500,1000,500,250,100

With MapGuide version 3.1.2 everything works as expected.
However, it turned out that in the latest beta version of MapGuide 4 at a scale of 1:100 (TileCoordinate z = 0) only white tiles are created.
All the other Scales are correct.

I tested this by using the MapGuide package that I created under 3.1.2 and then loading it into MapGuide 4 Preview 4. So, it is exactly the same configuration.

Maybe someone else has an idea what I could try. Otherwise I would open a ticket.

Thanks,
Gunter
