Wes Wannemacher commented on WW-2780:
-------------------------------------

James,
I could be reading this wrong, but maybe there is an NPE in ServletActionContext.getResult()... The NPE may just be bubbling up to his utility method. I would leave it open for now, but change the Fix Version to 2.1.4.

dapeng.ni,
Can you post the stack trace of the NPE you receive? that would help us to track down why this is happening.

> I use STRUTS in mixed env with other framework.  In 2.0.x ,  I create utility method to get HttpRequest.  It try to get request from ServletActionContext.getRequest(), if it return null, then get from another API.  
> But in 2.1.2,  if request is not from STRUTS,  ServletActionContext.getRequest() will throw NullpointException.. It is not good design. as I have to put try-catch even it just simply need a HttpRequest.
