About user overrides of configuration values
When specified in the configuration element settings, a user can edit certain aspects of the app at runtime.
If a configuration element was designated as app specific and to allow user overrides, the user can override the specified values while running the app on the device. For example, you might allow a user to change the look and feel of an app running on her device. In Mobile Client for HTML5, changes to configuration values are applied across all open tabs.
A user can encounter two experiences when overriding values, depending on whether the app includes the Show Config Items source element.
User experience without 'Show Config Items'
When the app does not include the Show Config Items source element, the user can make overrides on the App List before an app executes. To begin, the user selects the Mobile Client menu and App Configuration.
The App Configuration screen shows the user which apps allow her to choose new settings.
After selecting an app, the user is presented with a list of values she can change. When finished selecting new values, the user selects the arrow in the top left corner to return to the list of apps.
User experience with 'Show Config Items'
When the app does include the Show Config Items source element, the user can override values at any point in the app execution, depending on where the element was placed in the app flow.
In this example, the app was designed to first display the App Configuration screen at runtime. The user can select each element and make the desired changes. When finished, the user selects the arrow in the top-left corner to display the changed values in the app.
