Hi Martin, I had seen the configs in the struts-showcase, and used all of them as-is ; just added a javascript fn. to invoke DWR and was getting the NPE. So, looks like there's something broken in the default distro. I'll try your suggestion of using :
* public* ActionProxy createActionProxy(String namespace, String actionName, String methodName, Map<String, Object> extraContext, *boolean*executeResult, *boolean* cleanupContext); instead of : *public* ActionProxy createActionProxy(ActionInvocation actionInvocation, String namespace, String actionName, String methodName,*boolean*executeResult, *boolean* cleanupContext); Hope this is what you meant?
