Method Detail

renderHead

public void renderHead(org.apache.wicket.Component component,
                       org.apache.wicket.markup.head.IHeaderResponse response)

Prevent that we render the head more than once, because it is explicitly rendered before other head contributions. This way we force the initialization of the component registry before the initialization of child components, so Ext widget configurations can always be accessed in constructors of normal Ext components.

Specified by:

renderHead in interface org.apache.wicket.markup.html.IComponentAwareHeaderContributor

Overrides:

renderHead in class org.wicketstuff.js.ext.ExtObservable

Parameters:
