> - the image could not be found because there is no such parent component
Ok, I think begin to understand... but then I've a detailed question about AbstractPagableView/DataView. They are RefreshingViews and able to render as paginators. E.g. only first 10 items of 30. populateItem(...) is called only 10 times for first iteration. The second paginating request renders further 10 items and so on. How can the further/next items become part of the hierarchy? Whats the different between "Wicket renders the second 10 items" and "ComponentRenderer.renderComponent()" renders the second 10 items. How do items participate to the page hierarchy when wicket renders vs. ComponentRenderer renders?
