spring struts 2: Unexpected Exception caught setting 'lang' on 'class com.sun.proxy.$Proxy164

Rubens Gomes-4
I am using the Spring + Struts 2 Plugin, and I am getting an error from the Struts2 ParameterInteceptor (see below) when setting request parameters sent 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.

http://localhost:8080/locale/change-locale.do?lang=en&redirectURL=%2Fsecurity%2Fview-login.do

Hi,

seems to me like a issue with spring setup. Can you share that?

Re: spring struts 2: Unexpected Exception caught setting 'lang' on 'class com.sun.proxy.$Proxy164

I am back to *no* longer using the spring+struts plugin.  I chose to have actions be created by the struts framework instaead to avoid issues.
