Colors in JTable - unexpected result when scrolling

Question

Hi Guys,
Looks like I'm having a problem with a JTable.
I have a list of items and they are distinguished by 2 colors (so the end-user can differentiate between them). Anyway, the table colors work ok but when using a JScrollbar the table receives an unexpected result � few of the first items (which are not identical) share the same color.
anyone?
Example of an output (Gil will be colored Green, Dan Yellow, James Green�and so forth)
Gil
Gil
Gil
Dan
Dan
Dan
James
James
James
James
my code looks like this (I'll appritiate if someone can point out where I can have the html tags to display it correctly)
aTable = new JTable(dataModel)
public Component prepareRenderer(TableCellRenderer r, int row, int col)
Component c = super.prepareRenderer(r, row, col);
Color bg = Color.YELLOW;
String[] valuesRaw = (String[]) model.elementAt(row);
if (changeRround)
name1=valuesRaw[0];
changeRround=false;
name2=valuesRaw[0];
if (!name1.equals(name2))
this.switchColor(bg,c);
changeRround=true;
return c;
public void switchColor(Color bg, Component c)
if (colorSwitcher%2==0)
bg = new Color(221, 250, 207);
c.setBackground(bg);
c.setForeground(Color.BLACK);
else
bg = new Color(253, 252, 193);
c.setBackground(bg);
c.setForeground(Color.BLACK);
colorSwitcher++;
}

I'm getting there...
        aTable = new JTable(dataModel)
            public Component prepareRenderer(TableCellRenderer r, int row, int col)
                 Component c = super.prepareRenderer(r, row, col);
                 Color bg = Color.YELLOW;         
                 String[] valuesRaw = (String[]) model.elementAt(row);         
                 if (changeRround)
                     name1=valuesRaw[0];
                     changeRround=false;
                     name2=valuesRaw[0];
                 if (name1.equals(name2))
                 else
                     this.switchColor(bg,c);                    
                     changeRround=true;
                 return c;
             public void switchColor(Color bg, Component c)
                if (colorSwitcher%2==0)
                    bg = new Color(221, 250, 207);
                    c.setBackground(bg);
                    c.setForeground(Color.BLACK);
                else
                    bg = new Color(253, 252, 193);
                    c.setBackground(bg);
                    c.setForeground(Color.BLACK);
                colorSwitcher++;
            }
