You're actually not interested in the value change event. You are interested in the click event. The checkbox value remains the same. It's only the checked state which changes. It's the checked state which controls whether the value will be sent or not.

Use the click event instead and attach a listener on it.

<a4j:ajax event="click" listener="#{bean.changeActive}" render="tree">
