justin miller updated WW-4331:
------------------------------
Description:
ConventionUnknownHandler's handleUnknownActionMethod() always throws null which
causes a NullPointerException when using the Rest-Plugin. This method is called
due to RestActionMapper setting the default action method to "index" while the
ConventionUnknownHandler creates an ActionSupport proxy expecting the "execute"
method. Throwing null prevents the HandlerManager from handing off to the next
UnknownHandler in the list, if one exists. This is related to issue WW-3368.
Here's the abbreviated stack trace:
java.lang.NullPointerException
org.apache.struts2.convention.ConventionUnknownHandler.handleUnknownActionMethod(ConventionUnknownHandler.java:423)
com.opensymphony.xwork2.DefaultUnknownHandlerManager.handleUnknownMethod(DefaultUnknownHandlerManager.java:96)
