Do not call this method. This is a PHP magic method that we override
to allow using the following syntax to read a property:
$value=$component->PropertyName;
$value=$component->jsPropertyName; // return JavaScript literal
and to obtain the event handler list for an event,
$eventHandlerList=$component->EventName;
This will also return the global event handler list when specifing an 'fx'
event,
$globalEventHandlerList=$component->fxEventName;
When behaviors are enabled, this will return the behavior of a specific
name, a property of a behavior, or an object 'on' event defined by the behavior.
