I would like a feature in XWork that allows sub packages to override interceptors in the interceptor stacks (http://jira.opensymphony.com/browse/XW-554). What I want is that if I define an interceptor in a package with a name that already exists in parent packages, I want all the stacks that are using this interceptor to use the one defined in the local package instead, but only for this package and it's sub packages. The reason I want to be able to do this is so that I don't have to redefine all the stacks with my new interceptor, which would be particularly useful with the portlet plugin, which needs some tweaks to existing interceptors for them to work in a portlet environment. This is an area of XWork I have little experience with, and I've been digging through the XWork code base, but I have not yet found out how to achieve this. I guess I could either override the interceptors "configuration time", or at runtime. I'm not sure what happens when, and if/how I can modify the behaviour to do what I want. So if anyone have any ideas and pointers to where to start, I'd be grateful.
