Hi

I want to pause for a defined period of time per iteration of my for loop. I've tried using Thread.sleep(time) however this seems to just pause for a second and then do my entire loop, what gives?

  @Action  public void CycleElectrodeButtonPressed() throws InterruptedException {


for (int i = 0; i < 8; i++) 

     {

 cbarray.setSelected(true);

Thread.sleep(1000);



}
