Martijn, here Java is not safe as a language. Yo're able to invoke overrided methods on non-completely constructed objects.
from my perspective it is a regular case in Wicket: class SampleComponent extends ... { String parameter; SampleComponent(String id, String parameter) { super(id); this.parameter = parameter; } // method is called from within superconstructor @Override void createAdditionalComponents(RepeatingView rv) { useSomehow(parameter); } } I know two approaches to work around: - onBeforeRender - a closure as a constructor formal parameter. But the latter does not help with built-in components. If Wicket does not help us with adding appropriate method for second-step-initialization it should document it in wiki, javadoc and books "dear user, when overriding methods, beware using of yet unassigned constructor parameters". Hmm ... sounds stupid :) Martijn Dashorst wrote: > > This has been discussed till death previously and we have excluded it > from our roadmap.
