Form Option with Sling Model Exporter | Issue with datasource

[ckj0369]

Hi Team,

I'm trying to overlay form option.java to get the data in json format using exporter framework.
However, everything works as expected with the override and to get items data I've used:

@Override
    public List<OptionItem> getItems() {
        return superSelf.getItems();
    }

This method throws error when option is selected from Datasource ERROR [OptionsImpl.java] Failed to include the datasource at weretail/components/form/options/datasource/countriesdatasource
org.apache.sling.api.request.RecursionTooDeepException
Same works fine with Local and List.
