I was changing another part of the application when the something suddenly broke.
Caused by: java.lang.NoSuchMethodError: java.util.Set.java_util_Collection_contains(Ljava/lang/Object;)Z at com.google.gwt.user.client.ui.RootPanel.isInDetachList(RootPanel.java: 231) at com.google.gwt.user.client.ui.Widget.removeFromParent(Widget.java: 152) at com.google.gwt.user.client.ui.DockLayoutPanel.insert(DockLayoutPanel.java: 358) at com.google.gwt.user.client.ui.DockLayoutPanel.addNorth(DockLayoutPanel.java: 168) at com.kk_electronic.kkpilot.core.ui.WebPageLayout_UIBinderImpl.createAndBindUi(WebPageLayout_UIBinderImpl.java: 21) ... Has anybody experienced anything similar? The change I made was making a JavaScriptObject that implemented List<E>. can this somehow has caused the problem? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
