Sharing Data Between ViewsLocate this document in the navigation structure

Prerequisites

You have:

  • Created and embedded at least two views in the Mobile Project

  • Defined the navigation between the views

  • Created the required actions

  • Designed the view layout

Context

This process describes how you can share data between the different views in a component. To do this, you bind the data to a UI element, and then transport the bound data to the required view. To bind the data, you must assign a value reference between the:

  • Appropriate context of the component and view controllers, which references the data and UI

  • Property of the UI element, which binds the data

You can then implement transport of the data, as required. To implement dynamic transports of data between the views, you must write the appropriate Java code.

Procedure


  1. To transport data between views, you need a global space to store the data that comes from one view before it is passed on to the next. You create this global data storage space by using the component context.

  2. You map the elements of the view that contains the outbound plug to the elements of the component context.

  3. You create the necessary contexts for the view that contains the inbound plug.

  4. You bind the view context elements to appropriate UI elements by using the required properties.
