Form Option Datasource error in getItems()

Hi all,

I'm writing sling model with exporter framework to print JSON formatted output.

While rest all components work fine, there is some issue with form option component extended from core/wcm/components/form/options/v2/options.

I can get the output in Items when using the component with local and list.

But whenever using Datasource with correct datasource value then t throws following error:

Failed to include the datasource at weretail/components/form/options/datasource/countriesdatasource
org.apache.sling.api.request.RecursionTooDeepException

However same datasource works with normal rendering: http://localhost:4502/content/we-retail/us/en/user/checkout.html?wcmmode=disabled

Current code is as shown below, here superSelf.getItems() returns empty in case of datasource while in other case it works fine:

@9944223
public List<OptionItem> getItems() {
return superSelf.getItems();
}

Any help in this would be a great relief.
