Javadoc
Perform the action with a specific action event.
Normally this simply calls
#performAction(), that is using
the global node selection.
However you may call this directly, with an action event whose
source is either a node or an array of nodes, to invoke the action
directly on that nodes or nodes. If you do this, the action must
be such that it would be enabled on that node selection, otherwise
the action is not required to behave correctly (that is, it can
be written to assume that it is never called with a node selection
it is not enabled on).
But using a special action event in this way is deprecated;
better is to use
#createContextAwareInstance and pass
a lookup containing all desired Node
instances.
