Custom base map minimum scale fails to load in version 3.2

FrancoisPelletier

Hi,

We are having an issue since we upgraded to version 3.2 of the viewer and API. We use our own base map (ArcGISTiledMapServiceLayer) for a number of applications. Since 3.2, we've been having issue with the 1st zoom level (the one corresponding to the service's minimum scale) : Sometimes it loads, sometimes (most of the times) it doesn't...

Upon further investigation, we discovered that it fails to load when the map scale is higher than the tiled map service minimum scale. Ex. Our service minimun scale is set to 125000. When our application loads, the scale displayed in the "MapApplication.Current.Map.Scale" property is set to 125000.00000000001 and so tiles are not loaded and we have no base map... When zooming in and out, tiles sometimes actually appears but it's only when the map scale property is lower than 125000 (124999.99999999994).

The weird thing is that the scale values were the same in version 3.1 but somehow the tiles were always requested and displayed nonetheless.

So to sum up...
- Tiles are not requested in minimum zoom level since 3.2
- Tiles are loaded perfectly on any other zoom level
- Setting SnapToLevels to true didn't change anything
- No error displayed with fiddler, tiles are simply not requested to the server

I couldn't find anything related to this problem on this forum or any other so please, please help me !

Thanks

Just try to add "MinimumResolution" to 0.01 which used to work for me ..

<esri:ArcGISTiledMapServiceLayer ID="baseMap"  Url="https://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer " MinimumResolution="0.01" />

Thanks...
