Juraj Húska commented on ARQGRA-326:
------------------------------------

As there is a workaround, which does not make code more ugly, I have no urgent need to fix it. I would leave it till it is needed.

> If a Page Fragment is declared as inner class, then it can not access the fields of its outer class, as their are not inicialized by Graphene Enrichers, thus are {{null}}.
> The possible ugly workaround for such initialization can be:
> {code}
> if (pageFragment.getClass().getEnclosingClass() != null) { 
>            Field field = pageFragment.getClass().getDeclaredField("this$0");
>            field.setAccessible(true);
>            Object outer = field.get(pageFragment);
>            enrichRecursively(root, outer);
> }
> {code}
> It should be placed in some utility class, so it can be easily unit tested.
> There is one drawback of this method and that is, the outer class can not contain injection point for the inner class, otherwise it will cycle. The inner class can be obtained only dynamically via {{Graphene.createPageFragment}}.
