Application state variables

The following variables define the application state and are set in the url of the web page.

state variable name	location	type	example	default	description

App state propagation

A service watches the url parameters and updates the internal state variables. The application data manager and view manager watch the state variables for changes and make modifications to the view and data, respectively. Individual components watch the data for changes and update independently.
