The actual subset is determined by the data filter property.

The mixin adds spec.IData to the specification of an action.

dataFilter:  pentaho.data.filter.Abstract

When set to a filter specification, pentaho.data.filter.spec.IAbstract, it is converted into a filter object. Any registered visual filter type can be safely loaded synchronously.

When null, the action targets the entire dataset.

eventName:  string

Gets the event name of the action.

The default implementation returns the value of pentaho.action.Base.id.
