Nestor Boscan commented on WW-2198:
-----------------------------------
The DWRAction class invokes the interceptors assoiated with the Action. For
example if you have the Validation Interceptor it will call the validator
method and if it fails it not invoke the execute method. So it works great. The
original WebWork code also supported the execution of results

> Key: WW-2198
> URL: https://issues.apache.org/struts/browse/WW-2198
> Project: Struts 2
> Issue Type: New Feature
> Components: Integration
> Affects Versions: 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.0.7,

> In WebWorks there is a DWR and Struts 2 Integration using the DWRAction class
> where yo can invoke the Action methods using DWR. I implemented a similar
> class, but not with all the functionality with Struts 2. I've done a project
> with this integration and it works really great.

> ServletContext servletContext) throws Exception {
> ActionMapping mapping;

> In this case I'm invoking the actions method and returning the action to the
> JSP page so I can access attributes that were set in the invocation. It would
> be nice to have something like this part of the Struts 2 standard. If you
> need help implemening this solution I would gladly help.
