WroManager cannot be created using ServletContextAttributeHelper outside the request cycle

Hi,

I'm trying to use the new WroServletContextListener in my taglib (I used to 
parse wro.xml with a custom implementation).

Basically, I'm trying to have the following informations from the WroModel :
- to know all group names and the ResourceTypes
- to know which files are in a specific group

I want to do this in a ServletContextListener as well to pre-calculate these 
and other informations and when I do this :

        ServletContextAttributeHelper helper = new ServletContextAttributeHelper(servletContext);
        WroModel model = helper.getManagerFactory().create().getModelFactory().create();

I get the following exception:

I tried to use these lines in a ContextServletListener's contextInitialized or 
in a doTag (so during a request).

What is the correct way to get the WroModel ?

Thanks !
