Duplicate data when setValueAt is called
Hi,
I have 2 column 1st column contains the check box(isBold text) and 2nd column contains the text. What I want to achieve is when I click the checkbox in the table, the size of the text is change and will be concat when the size of the text if more than 10 char lenght. (e.g."I'm lazy to code" when I click the checkbox, the text in the cell will concat to "I'm lazy t"). But My problem is when I select other cell, like row 10 in the table...the previous text I entered is copied to the current selected cell. why?
I am using JTable and AbstractTableModel. Any idea, why it is copied? I've tried table.stopAllCellEditing(). But it still wont work.
publicvoid setValueAt(Object aValue,int rowIndex,int columnIndex){
MyObj obj = this.rows.get(rowIndex);
switch(columnIndex){
case 0: obj.setBoldText((Boolean)aValue).booleanValue());break;
case 1: obj.setText((String)aValue);break;
fireTableCellUpdated(rowIndex, columnIndex);
}
publicvoid setObjValueAt(String text,int rowIndex,int columnIndex,int len){
if(len == BOLD_TEXT){
if(text.length() > BOLD_TEXT){
text = text.substring(0, BOLD_TEXT);
}
this.textField.setLength(BOLD_TEXT);
}else{
this.textField.setLength(SIMPLE_TEXT);
}
this.textField.setText(text);
setValueAt(textField.getText(), rowIndex, 1);
}

All 3 methods above are included in MyTableModel class. If I try to modify row 1 col 1, and add the this text in the cell "Hello World" and click the Bold checkbox in row 1 col 0....The text is concat to char max of 10 which is "Hello Worl". The problem is when i select the new cell, row 3 col 1, the previous data "Hello Worl" is copied to the new selected cell. Why is that? Grilled said that it fires the event again in the new cell which is correct...but I wanted to fire the event so that the cell in col 1 is always updated(char length size and concat according to char length set in the cell) when the user clicks the checkbox in col 0.
public class MyApp extends JPanel{

}

public void setValueAt(Object aValue, int rowIndex, int columnIndex) {
MyObj obj = this.rows.get(rowIndex);

case 1: obj.setText((String)aValue); break;
}
fireTableCellUpdated(rowIndex, columnIndex);

if(len == BOLD_TEXT){
if(text.length() > BOLD_TEXT){

}else{
this.textField.setLength(SIMPLE_TEXT);
}
this.textField.setText(text);
setValueAt(textField.getText(), rowIndex, 1);
}
public boolean isCellEditable(int row, int col) {
if(col == 0) return false;

setValueAt(true, row, 0);

setObjValueAt(text, row, 1, BOLD_TEXT);
}else{

}

}

Here's the SSCCE you've requested. Hope there are solutions.
Thanks in advance.
