(After the object is completely deserialized and the listeners are attached it fires an update event to them.) But I wasn't really able to run the unit tests of JFreeChart easily (some free swing breakage makes it impossible to select a test...). If you are able to run the unittests against a recent GNU Classpath from CVS that would be appreciated. I checked in my latest fixes now. Thanks, Mark
