Will renderHead method be invoked when a component is rendered via wicket events?
I am using bootstrap-timepicker.js in a single page application .
Time picker is added in a panel which is then embedded in the page. When
the entire page is reloaded, the timepicker is working fine. However, when
the respective panel is displayed via Wicket events, the time picker is not
rendered. I am using Component#onEvent(Ievent) method to display the panel.
The javascript resource reference for timepicker is added in renderHead
method. I would like to know if a panel is reloaded during onEvent call,
will rendeHead method be invoked or not?
Here are few code snippets to help you all understand what I am trying?
public class BasePage
{
public void renderHead(IHeaderResponse response)
{
response.render(JavaScriHeaderItem.forReference(new
JavaScriptResourceReference(bootstrap-timepicker.js)));
response.render(JavaScriHeaderItem.forReference(new
JavaScriptResourceReference(common.js)));
}
//event is received to display panel
public void onEvent(IEvent ievent)
{
super.onEvent(ievent)
if(event.getPayLoad() instance of Notification)
{
Notification notification = (Notification) event.getPayload();
PageParameters parameters = notification.getPageParameters()
Panel selectedPanel = getSelectedPanel(parameters,
notification.getPanelClass);
BasePage.this.selectedPanel.replaceWith(selectedPanel);
}
}
}

Hi,
If a component is rendered then its #renderHead() should be called!

Call super.renderHead(response) too.
Is this a method in the page or in SelectionPanel ?!

There is no Ajax here, so the whole page is re-rendered and #renderHead()
should be called for all visible components.

Sorry here ajax is involved. In the sample code i forgot to
add.
selectedPanel.setOutputMarkupId(true);
notification.getTarget().add(selectedPanel);

In that case only selectedPanel's #renderHead() will be called.
BasePage#renderHead() won't be called because the page is not re-rendered
with the Ajax response.
