Hi,
I think you just need:
class MyComponent extends SomeWicketComponent {
@Override public void renderHead(IHeaderResponse response) {
response.renderOnDomReadyJavascript("someJSToExecute()");
}
}
someJSToExecute() will be executed every time an instance of MyComponent is
rendered. Both Ajax and normal requests.
