I'm presently refactoring a JTable which displays a multitude of different types of data. The primary reason for this refactoring is that there a few ClassCastExceptions (the author/friend who wrote the code is off on hiatus), and I can't seem to find where these are originating from.

When you edit a cell in an jtable the value is made permanent only if the focus is changed or if one hits enter (for example if you change the cell value from "abc" to "xyz" and close the window the edit is lost).
