After successfully replicated this article: Extending Adobe Experience Manager Core Components Now I have been trying to extend but the Core Form Options component. However I'm getting problems related with its items related class. It also turns out that the core List component has a similar context and it also fails with the same following error:
It seems like they might require a special way to annotate or something else because doing it just in the way the Title component was done in the article. The code it does build correct, but at runtime is when I get the exception.
Do you guys have perhaps an example on how to work that around?
