ArcGIS Viewer Add-In FAQ

• How do I get the add-ins to work properly?

  The most common mistake is to attempt to add the tools directly without adding the behaviors on which they depend. The Navigation add-in has two behaviors which must be added: Navigation Behavior and Tool Manager Behavior. The Query add-in has one behavior which must be added: Query Behavior. In addition, the Query Add-in will not work unless the Navigation add-in behaviors have been added.

  Other prerequisites exist as well:
  

  1. The map must have a graphics layer with no rendering restrictions. The layer should be topmost in the map.
  2. The map must have at least one dynamic map layer, and the bottommost dynamic map layer must be on a server that has an active geometry service with a URL of the following type: http://.../services/Utilities/Geometry/GeometryServer

• Why are the tools acting strangely and/or causing errors in Application Builder mode?

  The behaviors are not designed to work in Application Builder mode. They assume, upon loading, that they are in a fresh web session.

• How can I create my own tools with custom mouse cursors?

  Inherit from the NavTool class. Download and study the code for the Navigation add-in for examples.

• Why does Application Builder act buggy when I'm modifying existing applications? Is there a best practice?

  Application Builder acts buggy because it is buggy. The best practice is to use Application Builder only to create a new application, and then edit the config files manually thereafter.
