Application Methods

Control panel declares some methods in the aps.app namespace that application views can define or re-define to specify the needed behavior of those methods.

Workflow

In the single page technology, each of the application UI view contains 4 flow methods that the UX1 calls one after another: init, onShow, onContext, and onHide.

METHOD	DESCRIPTION
init	Initializes the view when the user opens it for the first time. Normally, it returns a hierarchy of widget objects that UX1 loads. UX1 does not call this method when it opens the view for the second and any subsequent time.
onShow	Used to prepare widgets before making them visual. For example, it can reset the widget contents once the user opens the view for the second and any subsequent time.
onContext	The main data processing method. It queries data sources and then refreshes the widgets.
onHide	Prepares the view for closing. UX1 calls this method when the user navigates to another view or quits UX1.

Transition

UX1 detects if a navigation button declared in the view metadata is clicked. Once it happens, UX1 triggers an event that the respective handler in the current application view processes.

METHOD	DESCRIPTION
onCancel	Processes the Cancel button on-click event.
onNext	Processes the Next button on-click event. It is used, when the view is a wizard step.
onPrev	Processes the Previous (Back) button on-click event. It is used, when the view is a wizard step.
onSubmit	Processes the Submit button on-click event.
