Non-serializable Attribute exception from Portlet if using e
I've deployed my own JSR-168 Portlets from my own WAR file and they show up in the manager fine. I can create instances using the management portlet as well. As soon as I add one of my instances to any page in the portal, if they use expiration-cache > 0, I get the exception that follows.
I'm using the jboss-portal-2.2.0-bundled (binary) version. All standard settings ... basically unzipped and executed run.bat and deployed my WAR.
Why am I posting as the error seems obvious you may ask ...
First, these portlets are known to work fine in Liferay, Pluto, and WebLogic. I only mention this so that you don't waste your time thinking there is a problem with my portlet implements.
Second, the only attribute I use in the entire Web application (Servlets/JSP/Portlets) is one object that I put into the application context. I added a quick out-in Serialization test and that object is definitely Serializable. I do not use the portletSession, session attributes, or request attributes. My impl couldn't be more trivial. So this error really makes no sense...
Lastly, if I set <expiration-cache>0</expiration-cache> in portlet.xml, then the Portlet renders fine. So I have a work-around at this point, but I'd like to turn caching on at some point.
Can you shed some light on why I'm getting this from the cache interceptor?
