Hi everyone,
I have an issue at JSONInterceptor/ParameterInterceptor (i think),
parameteres are being lost (becoming null), im using:
* Struts2 2.3.16.3
* Spring AOP 4.0.2
* Tomcat 7.0.34
* Dojo 1.8
After many debugging i've concluded that the issue it's inside one of
those two interceptors, this is the issue:
At client side i send the following json-rpc/stuff, please pay special
attention to POST-DATA and the red parameter
characterEncoding = UTF-8
contentLength = 872
contentType = application/json-rpc
locale = es_MX
locales = es_MX

Previews data was printed at a Filter i've made for debugging
purposes, it runs before any struts interceptor (RequestBuffer.java)
(the failure happens with and without my filter)
The stack trace shows an error inside my application because the
red-id parameter didn't made it to my function called "HQLT_findById",
actually a null was sent there

At the end, the issue is that i've sent this:
*{"author":{"id":302},"autoProm":0,"autorizationPool":null,"blockedBy":null,"blockedByName":null,"businessUnit":null,"code":"","creationDate":"2014-07-30T12:36:37","deleted":0,"department":{"id":"13"},"description":"BITACORA

But the /JSONUtil.deserialize (at JSONInterceptor:123)/ inside of
struts did this (please note that *"id":_41201_* is missing) (the
following JSON was made by using /JSONUtil.serialize /of my Entity
/[ignoring hierarchy and excluding nulls//]/)
*{"author":{"id":302},"autoProm":0,"creationDate":"2014-07-30T12:36:37","department":{"code":"","deleted":0,"description":"","id":13,"status":1},"documentCode":"FFQ-043","documentType":{"code":"FORMATOS","deleted":0,"description":"FORMATOS","id":11,"isRetainable":1,"moduleId":0,"status":4,"value":"11"},"fileId":12820,"flujo":{"code":"","deleted":0,"description":"","id":24,"status":1},"nodo":{"code":"","deleted":0,"description":"","id":3575,"status":1,"topLevel":0},"reazon":"FORMALIDAD

I've inspected a lot of struts2 source code and i didn't found
anything, my guess is that somewhere inside struts something like
/request.getParameter("id")/ is beign called or simply
/JSONUtil.deserialize /is not working properly.
The issue is not easily reproducible because it happens like 1 time
per day, some important fact is that once it happens ONCE at any SMD
call it starts happening at ALL SMD calls... the only fix for this is
to restart Tomcat, after that the application starts working fine again,
A workaroud i did by following the /request.getParameter("id")/ guess
was to do a HttpServletRequestWrapper to make "getParameter"
multireadable, by using this workaround the error stoped happending by
20 days... but suddenly it happeed again, the following link shows my
HttpServletRequestWrapper
* http://codeviewer.org/view/code:4241
Basically it stores all RequestBody data to be able to call request
data more than once (getParameter, getParameters, getInputStream,
etc), if you need more information i'll be happy to help,
Greetings
