and the java to:
public class Home extends BasePage {
public void okListener(IrequestCycle cycle) {
cycle.activate("Result");
}
}
IActionListeners are create for you by Tapestry and hooked to the
methods with sigs as above. These synthetic listeners are stored in a
map called "listeners" hence the ognl expression
"listeners.okListener".
