GACDataSource
The data used in a UI element like FlashIsland 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 a 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 (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 is ensured.
● The FlashIsland is independent from the actual context.
For performance reasons you may not want to transfer all attributes/subnodes and their attributes, application developers must explicitly declare the attributes/subnodes and their attributes that they want to send. The attributes to be sent are collected together in the GACProperty aggregation, whilst you declare subnodes using CHILD_DATA_SOURCES aggregation.
A FlashIsland can also have several GACDataSources.
The integration of GAC* controls in Web Dynpro ABAP dialog boxes (popups) is not supported.

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