If you're unit testing and using the ActionProxy and your Action has a ServletDispatcherResult, you'll need to mock up the Request, etc...
I would suggest that if you're unit testing you just set your properties on your Action instance that you create yourself and execute it. You don't need to unit test our framework, we do that for you :-) Jason > -----Original Message----- > From: Jirong Hu [mailto:[EMAIL PROTECTED] > Sent: Saturday, December 27, 2003 9:07 AM > To: [EMAIL PROTECTED] > Subject: [OS-webwork] java.lang.NullPointerException at > System.out.println(proxy.execute()); > > > Hi, > > First touch with WebWork2.
