BUG; jdk1.3; Gridcontrol; Attention JDeveloper Team

Question

I have found yet another bug in the implementation of gridcontrol and jdk1.3.
I have the following renderer for my text fields.
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
* A Class class.
* <P>
* @author Linda B. Rawson
public class DefaultTextRenderer extends DefaultTableCellRenderer
* Constructor
public DefaultTextRenderer() {
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
Component comp = super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
String myFlag = "";
try {
// this row index must correspond to the run flag column in the gridcontrol
myFlag = (table.getValueAt(row,15).toString());
myFlag = (myFlag == null) ? "" : myFlag;
if (myFlag.equals("P") ) {
comp.setBackground(Color.lightGray);
} else if (myFlag.equals("S") ) {
comp.setBackground(Color.yellow);
} else if (myFlag.equals("F") ) {
comp.setBackground(Color.red);
} else {
comp.setBackground(Color.white);
} //This is to catch the null row in gridcontrol from jdev bug
catch (NullPointerException e) {
return comp;
I implement the renderer like this:
DefaultTextRenderer textRenderer = new DefaultTextRenderer();
TableCellRenderer renderer;
renderer = textRenderer;
m_table = gridControl.getTable();
m_table.getColumnModel().getColumn(1).setCellRenderer(renderer);
In JDK 1.2 it colors the appropriate row just like I want.
In JDK1.3 it will not do the first occurance of the row. In otherwords if I want the first row in the grid colored it fails.
You need to test this in your upcoming version.

Hi,
we have faced similar compatibility problems
when testing our application using JDEV3.2
and JDK1.3 (Browser crashed);
Since we use JDK1.3.1 (it has been released aready by SUN) this severe problem vanished.
I really share your concerns about the grid
control in JDEV3.2.3 and I hope that we find
a way to track the successful treatment of
BUG 1806180!
Have fun
