Serializtion problem with Event Listeners

I'm currently implementing serializtion for a JComponent derived object
that has several listeners added to it.  When serializing it,
JComponent attempts to serialize all of the listeners as well.  This is
not what I want since when it is read back in it will create a whole
series of objects that aren't needed.

For example, if I create an object called FooDaddy that creates several
objects called FooChild and sets itself as a listener to each.  And
then try to serialize one of the FooChild objects, it will also
serialize the FooDaddy object.  When I deserialize FooChild it will
create a new FooDaddy.  I then have two FooDaddy objects!! I then have
a custody battle to contend with :-)

Short of implementing my own serialization field by field, is there a
way around this?  Why would anyone want to serialize event listeners? 
I was sure Sun would make this list transient until I ran into this
problem.
