You may want to post your code so people can see exactly what is going on.

thanks John for your reply, i am using TableSorter class from sun web site. It works fine when the i have static data, but i am getting data from the stock market, so it is changing, here is the link for tableSorter

private Row[] getViewToModel() {
if (viewToModel == null) {
int tableModelRowCount = tableModel.getRowCount();
viewToModel = new Row[tableModelRowCount];
for (int row = 0; row < tableModelRowCount; row++)
{
viewToModel[row] = new Row(row); <--THIS IS THE LINE
CAUSING THE EXCEPTION
}

if (isSorting()) {
Arrays.sort(viewToModel);
}
}
return viewToModel;
}

Why would a Null Pointer Exception be occurring here if we are assigning a value???

thanks in advance

i have solved the problem, here is the solution we need to inform tableSorter by using Event Thread e.g

**********************************************************************
try{
SwingUtilities.invokeAndWait(new Runnable() {
public void run() {
tableModel.fireTableDataChanged();
}

});
}catch(InterruptedException ie){

}catch(InvocationTargetException te){

}

**********************************************************************
