<pre><span lang="EN-US" style="color:black">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:<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black"><o:p> </o:p></span></pre>
<pre><span lang="EN-US" style="color:black">500000,250000,100000,50000,25000,10000,5000,2500,1000,500,250,100<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black"><o:p> </o:p></span></pre>
<pre><span lang="EN-US" style="color:black">With MapGuide version 3.1.2 everything works as expected.<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black">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.<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black">All the other Scales are correct.<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black"><o:p> </o:p></span></pre>
<pre><span lang="EN-US" style="color:black">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.<o:p></o:p></span></pre>
<pre><span lang="EN-US" style="color:black"><o:p> </o:p></span></pre>
