struts2-json-plugin: ExecuteAndWait issue when returning JSON

Hi All,

While upgrading from Struts 2.5.30 to 6.1.1, I found an issue when using the ExecuteAndWaitInterceptor, if the action returns JSON data. I believe the issue was introduced in version 6.0.0 on WW-5070. The JSONResult.findRootObject(...) method was changed to call 'stack.findValue("#action")' instead of 'stack.peek()' to get the root object. This results in the polling action being returned instead of the original action that was executed, causing data to be missing from the final response.

Workaround:
Changing the action to implement 'ModelDriven' reinstates the old behaviour of calling 'stack.peek()' in the JSONResult.findRootObject(...) method.

Thanks,

Kris
