Hello,

Another question about something completely different... How can I
propagate an exception through an event handler? Each time I do
something to my dataset I have to write try..catch blocks for
"DataSetException". What I would like to do is throw this exception for
now, but if I throw it then I have problems back in init where the event
handler was declared.  As I recall, this is a nested class so is it
possible to still handle this exception in the main class (and not the
nested subclass)? Here is an example of my code:

//////////////////////////////////////////////////
// Here is what I usually write to make it work...
//////////////////////////////////////////////////

void jbInit() throws Exception {

  button5.addActionListener(new java.awt.event.ActionListener() {
      public void actionPerformed(ActionEvent e) {
        button5_actionPerformed(e);
      }
  });

}

void button5_actionPerformed(ActionEvent e) {
    try{
      dsTestPlan.deleteRow();
    }
    catch ( DataSetException ex ) { }
}


///////////////////////////////
// This is what I want to do...
////////////////////////////////

void jbInit() throws Exception {

  // How do I deal with the thrown exception here ???
  button5.addActionListener(new java.awt.event.ActionListener() {
      public void actionPerformed(ActionEvent e) {
        button5_actionPerformed(e);
      }
  });

}

void button5_actionPerformed(ActionEvent e) throws DataSetException{
  dsTestPlan.deleteRow();
}


Thanks,

-Bob
