Too small zoom level for address search

Problem:

When zooming in on the house number from the address search in UT Click Before You Dig, the zoom is too strong. This causes the map image (open street map) to disappear and thus the desired address is no longer visible.

Cause:

The behavior is caused by a lack of zoom level configuration when using tiled services.

Solution:

In the client.config, appropriate zoom levels must be defined via the configData.lods parameter. The available lods of a tiled service can be queried via its REST interface. For example: http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer?f=pjson

The following is a possible example configuration.

configData.lods = [{
