hi all,

I wrote a customized renderer for a JTable but it is behaving
differently from what I expected: even if I just acted on the
BACKground color, when this render is selected the table does not show
the content of the cells. Double-clicking on a cell shows the data
correctly sorted in it but, as soon as the cell is de-selected, data
re-become invisible.

Here is the code: can anybody please tell me what am I doing wrong?
