Currently, developers can declaratively attach listeners for user interface and property change events in FXML. However, collection events are not yet supported. A caller should be able to attach a listener to a List or a Map as follows:

<FXCollections fx:factory="observableArrayList" onChange="handleListChangeEvent(event)"/>
<FXCollections fx:factory="observableArrayList" onChange="#handleListChangeEvent"/>

<FXCollections fx:factory="observableHashMap" onChange="handleMapChangeEvent(event)"/>
<FXCollections fx:factory="observableHashMap" onChange="#handleMapChangeEvent"/>
