[exoplatform] Re: Problem instanciating a component via reflection

["Luis Arias" <kaaloo@xxxxxxxxx>]

Thanks Benjamin,

I imagine that we also need a filter mapping for the ThreadLocalSession 
filter ?

   <filter-mapping>
    <filter-name>ThreadLocalSessionProviderInitializedFilter</filter-name>
    <url-pattern>/rest/*</url-pattern>
  </filter-mapping>
