Hello,
I develop apps in Richlet/Java. I have defined an error page in zk.xml like so:
<error-page> <exception-type>java.lang.Throwable</exception-type> <location>CriticalError.zk</location> </error-page>
Somehow I have managed to get a 500 error from Tomcat for an uncaught exception. How did this happen? I thought the error page should be used instead.
For interest, I tried to do something silly like add a Menuitem directly to a Menu in a Listitem of a Listbox. I got this error:
org.zkoss.zk.ui.UiException: Unsupported child for menu: <Menuitem null> org.zkoss.zul.Menu.insertBefore(Menu.java:110) org.zkoss.zk.ui.AbstractComponent.appendChild(AbstractComponent.java:1032) sanitized.Publish$4.createCellComponent(Publish.java:208) sanitized.renderCell(AbstractListTableCellRenderer.java:18) sanitized.render(ListTableRowRenderer.java:96) org.zkoss.zul.Listbox$Renderer.render(Listbox.java:2289) org.zkoss.zul.Listbox.onInitRender(Listbox.java:2179) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:585) org.zkoss.zk.ui.impl.EventProcessor.process0(EventProcessor.java:211) org.zkoss.zk.ui.impl.EventProcessor.process(EventProcessor.java:143) org.zkoss.zk.ui.impl.EventProcessingThreadImpl.process0(EventProcessingThreadImpl.java:488) org.zkoss.zk.ui.impl.EventProcessingThreadImpl.run(EventProcessingThreadImpl.java:422)
Of course I know what's causing the crash but I can't figure out why it isn't handled by the error page. I can't even get a breakpoint at Publish.java:208 to catch the debugger.
Thanks for any insight.
