    Default Serializing Listeners

    I have an object that extends JFrame and contains a MouseListener and 3 ActionListeners. After I serialize the object and restore the object, none of the listeners respond any more.

    Is there something special that needs to be done with Listeners in order to serialize them?

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.

    Default Re: Serializing Listeners

    Long story short: the listener implementation that Swing uses is a transient array - in other words the registered listeners for swing components are not serialized. You could try and use a variety of methods to restore these listeners upon reading the object. My .02, but you might want to consider a different method to save things (I would typically discourage one from saving data in this manner - depending upon what you are doing - as other formats are more flexible to changes to the client/GUI without things breaking)
