DevFaqWeakListenerWhen
You should use a WeakListener any time you are adding a listener to an object, but there is no code - and possibly no opportunity - to explicitly remove it.
If the thing you are listening to does have some kind of observable life-cycle, it is preferable to explicitly add and detach listeners.
But in the case that you are adding a listener which is never explicitly removed, it is good form to use WeakListeners

Apache NetBeans is an effort undergoing incubation at The Apache Software Foundation (ASF).
Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.
While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
This wiki is an experiment pending Apache NetBeans Community approval.
