I don't understand how the getTileUrls are getting the BBOX. I'm trying to retrieve my map from a WMS map provider. The getTileUrls keeps getting the wrong bbox.

My map extent is MapExtent( 0.043075 , 0.0 , 90.0 , 90.064325 )

I set the center of the map to:
map.setCenter(new Location(0.0,90.0));

Here is the result when I launch the map it request these tiles:

&BBOX=-90.02197,0.04395,-90.00000,0.06592
&BBOX=-90.02197,0.02197,-90.00000,0.04395

When I click the center of the map to get the location I get the correct spot, but the url request are requesting the wrong spot.

If I move my map extent to MapExtent( 0.043075 , 0.0, -90, -89.935675 ), it will work - my map will show up.

Is it possible for me to get the source code for this map application?

The site said the map was made by Koordinates. The interface look very nice. I was wondering if I can get something similiar to them.
