GACDataSource

The data used in a UI element such as FlashIsland or SilverlightIsland is represented by a GACDataSource among other things. The data can thus be represented with a GACDataSource as well as via GACProperty UI element. For GACDataSource, the data must come from an x..n node.

GACDataSource is used to transfer tabular data. There are two important factors:

• The node involved (property dataSource)
• The name of the list to fill in the Flash application (Silverlight application) (property name)

The GACDataSource is bound to a Web Dynpro context.Each GACDataSource has a set of properties that are bound to context attributes of the GACDataSource node or subnode. This has the following advantages:

• Programming is possible as in Web Dynpro.
• The automatic transport of data from and to the FlashIsland/SilverlightIsland is ensured.
• The FlashIsland/SilverlightIsland is independent from the actual context.

Since, you may not want to transfer all attributes/subnodes and their attributes for performance reasons, application developers must explicitly declare the attributes/subnodes and their attributes that they want to send to FlashIsland/SilverlightIsland. The attributes to be sent are collected together in the GACProperty aggregation, whilst you declare subnodes using CHILD_DATA_SOURCES aggregation.

A FlashIsland/SilverlightIsland can also have several GACDataSources.

For dynamic programming, the same properties, events, and aggregations as in the View Designer are available. Bear in mind the different spellings.
