This is because jMemorize overrides the JTable.columnMarginChanged that
is fired from the JTable constructor, when the user - derived class is
not yet initialised. This can be easily fixed by initialising the table
column model befor the table listeners are installed on it, I have
comitted such patch. Unfortunately, this brings us to the second
exception, related to the JFreeChart:

Probably our JFreeChart experts could look at this.

Hi,
I added jMemorize[0] to the list of Free Swing apps. I just stumbled over the

Since there are some Swing hackers who frequently work on JTable this might be a
low hanging fruit for them.
