A cell renderer is an object that provides a Component that will be
used to do the painting.  Normally, the getListCellRendererComponent()
method will configure the properties of the Component so it will render
the cell appropriately.

As is often the case, this cell renderer returns the same component
each time getListCellRendererComponent() is called.  Since the above
code configures the "Selected" property only if cellHasFocus is true,
it will be left in whatever state it was in previous time it was used.

So you need to change the code to set the "Selected" property even when
"cellHasFocus" is false.

    if (cellHasFocus) {
        if (isSelected) {
            setSelected(false);
        }
        else {
            setSelected(true);
        }
    }
    else {
        setSelected(true);
    }

Of course, these 11 lines of code could be replace with the following
single line:

    setSelected( cellHasFocus & !isSelected );

This is much simpler and more efficient and it also makes it far more
clear that the "Selected" property will always be set.

BTW, many people frown on anonymous messages.  I can understand why you
might want to omit your e-mail address, but I can think of no reason to
omit your name.
