Let see if this answer your question, in my example i have this Interface:
[AjaxEventResponseListener] as root Event interface
Then i have 2 more specifics interfaces named: [MyHomePageEvent1] and
[MyHomePageEvent2]
Now i have 2 panels component:
1-> CounterPanel extends Panel implements MyHomePageEvent1
2-> MessagePanel extends Panel implements MyHomePageEvent2
And in finally in HomePage i added them and provide several link to test
them:
<code>
add(new AjaxLink<Integer>("counterInc1") {
@Override
public void onClick(final AjaxRequestTarget target) {
HomePage.this.updateCounter();
propagateAjaxEvent(MyHomePageEvent1.class, target); //Only CounterPanel
get Updated
}
});
add(new AjaxLink<Integer>("counterInc2") {
@Override
public void onClick(final AjaxRequestTarget target) {
HomePage.this.updateCounter();
propagateAjaxEvent(MyHomePageEvent2.class, target); // Only MessagePanel
get Updated
}
});
add(new AjaxLink<Integer>("counterInc3") {
@Override
public void onClick(final AjaxRequestTarget target) {
HomePage.this.updateCounter();
propagateAjaxEvent(AjaxEventResponseListener.class, target); // Both Panel
get Updated
}
});
</code>
Are we on the same page?
