I am using the Spring + Struts 2 Plugin, and I am getting an error from the=
 Struts2 ParameterInteceptor (see below) when setting request parameters se=
nt on the URL.  My Actions are being created by the Spring factory.  And I =
*do* have the proper properties setters in my class (see below).

In the URL below, the "lang" and "redirectURL" , both lang/redirectURL are =
not being set.
