Hi, I'm on wicket (core & extension) 1.4.12 & (Wicket Spring & IOC 1.5-M1).
On the following scenario I get the error trace : java.lang.NoClassDefFoundError: org/apache/wicket/util/lang/WicketObjects at org.apache.wicket.spring.SpringBeanLocator.getBeanType(SpringBeanLocator.java:222) at org.apache.wicket.spring.SpringBeanLocator.locateProxyTarget(SpringBeanLocator.java:243) at org.apache.wicket.proxy.LazyInitProxyFactory$CGLibInterceptor.intercept(LazyInitProxyFactory.java:317) at WICKET_com.neurosys.pms.site.wicket.model.ProductSortableDataProvider$$EnhancerByCGLIB$$b2f1a79d.detach(<generated>) at org.apache.wicket.markup.repeater.data.DataViewBase.onDetach(DataViewBase.java:150) at org.apache.wicket.extensions.markup.html.repeater.data.grid.AbstractDataGridView.onDetach(AbstractDataGridView.java:159) at org.apache.wicket.Component.detach(Component.java:1221) at org.apache.wicket.MarkupContainer.detachChildren(MarkupContainer.java:1680) at org.apache.wicket.Component.detach(Component.java:1243) at org.apache.wicket.MarkupContainer.detachChildren(MarkupContainer.java:1680) at org.apache.wicket.Component.detach(Component.java:1243) at org.apache.wicket.MarkupContainer.detachChildren(MarkupContainer.java:1680) at org.apache.wicket.Component.detach(Component.java:1243) at org.apache.wicket.MarkupContainer.detachChildren(MarkupContainer.java:1680) at org.apache.wicket.Component.detach(Component.java:1243) at org.apache.wicket.request.target.component.PageRequestTarget.detach(PageRequestTarget.java:80) at org.apache.wicket.RequestCycle.detach(RequestCycle.java:1122) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1462) ... ... I have a DataTree, (mentioned in http://apache-wicket.1842946.n4.nabble.com/Ajax-Panel-Update-td3057421.html - Ajax Panel Update). On clicking a node, it refreshes an adjacent Panel (Lets call it PRODUCT LISTING). On that Adjacent panel, when I click on an entry It create a popup using pseudo-code : Link link = new BookmarkablePageLink (id, productDetails.class, params); link.setPopupSettings(<PopupSettings Object>); On "onInitialize" of the panel PRODUCT LISTING ; uses a DataProvider that detaches. It is here where this exception gets generates. As is evident from the Trace. I found that "org/apache/wicket/util/lang/WicketObjects" is not there in any of the Wicket/Wicket-Spring JAR's I have.
