public static final Object oldValue
List decorator that will trigger PropertyChangeEvents when a value changes.
An optional Closure may be specified and will work as a filter, if it returns true the property will trigger an event (if the value indeed changed), otherwise it won't. The Closure may receive 1 or 2 parameters, the single one being the value, the other one both the key and value, for example:
 // skip all properties whose value is a closure
 def map = new ObservableList( {!(it instanceof Closure)} )

 // skip all properties whose name matches a regex
 def map = new ObservableList( { name, value -> !(name =˜ /[A-Z+]/) } )
 
The current implementation will trigger specialized events in the following scenarios, you need not register a different listener as those events extend from PropertyChangeEvent

Bound properties
