> After toggling visibility of the BorderBodyContainer to false the
> Page.checkRendering method fails in line 1157, claiming an iterator
> IllegalStateException. This happens because iterator.remove() is called twice
> for a child component in the border component, if the body is not visible.
> My Code:
> public class TogglePanel extends Border {
> private boolean expanded = true;
> public TogglePanel(String id, IModel<String> titleModel) {
> super(id, titleModel);
> Link link = new Link("title") {
> @Override
> public void onClick() {
> expanded = !expanded;
> getBodyContainer().setVisible(expanded);
> }
> };
> link.add(new Label("titleLabel", titleModel));
> add(link);
> }
> }
> Markup:
> <wicket:border>
> <h3 class="collapse" wicket:id="title">
> <span class="label" wicket:id="titleLabel">Panel Title</span>
> <a class="foldicon"> </a>
> </h3>
> <wicket:body />
> </wicket:border>
