DMF and ExecutionContext.getCurrentContext()

[VANKEISBELCK Remi-2]

Hi folks,

I'm using DMF with a custom ActionResolver.
In MyActionResolver.getActionBeanType(String path), I need to access
ExecutionContext.getCurrentContext(), unfortunately it returns null.

The code in MyActionResolver goes like :

  public Class<? extends ActionBean> getActionBeanType(String path) {
    ActionBeanContext ctx =
ExecutionContext.currentContext().getActionBeanContext(); // throws
NPE
    try {
      ActionBean bean = getActionBean(ctx, path);
      if (bean!=null) {
        return bean.getClass();
      }
      return null;
    } catch (StripesServletException e) {
      return null;
    }
  }

As you see, it simply delegates to getActionBean(actionBeanContext,
path), so I use ExecutionContext.getCurrentContext() in order to
retrieve the current ActionBeanContext. I need to get the bean
context, as my action resolver is fully dynamic (action beans are not
known at startup time)... but I have this NPE.

I've investigated a bit, and I could see that the DMF calls
actionResolver before invoking the dispatcher, which is the one which
initializes the context :/

Using regular StripesFilter/Dispatcher web.xml config (without DMF),
or with MockRoundtrip, it works smoothly...

I'm kinda stuck, I don't want to hardcode those url mappings in web.xml... :/
Is there any way to get around this ?

Thanks in advance for any advice...

Cheers

Remi

I was thinking, I only need the HttpServletRequest to get the job done
in my ActionResolver, not the full ActionBeanContext...

Is there any way to do this, that would not rely on
ExecutionContext.getCurrentContext(), and thereby that would work with
DMF smoothly ?

Thanks

Cheers
