org.olat.core.gui.control.state.ExtendedControllerState
Description:
a state represents the state of a controller.
@author Felix Jost

    // compare all controllerstates
    int osize = other.getExtendedControllerStateCount();
    if (osize != extStateList.size()) return false;
    // H: at least the same number of entries: now we must compare one by one
    for (int i = 0; i < osize; i++) {
      ExtendedControllerState ostate = other.getExtendedControllerStateAt(i);
      ExtendedControllerState mystate = this.getExtendedControllerStateAt(i);
      if (!ostate.isSame(mystate)) return false;
