GACEvent Events 

Events in View Designer

●      onAction

Event if an action can be executed.

Parameter Name	Type	Description
ID	STRING	Standard parameter
CONTEXT_ELEMENT	IF_WD_CONTEXT_ELEMENT	Standard parameter

Event parameters defined using the aggregation parameters are also transferred. Parameter name and type correspond to the entries in the GACEventParameter UI elements. If the parameter name does not adhere to the naming conventions of ABAP parameters (length <= 30, upper case only, etc.), and therefore cannot be defined as method parameters in the action handler, the parameters can still be accessed using the wdEvent object.
