Hi everyone,  
I have a issue with the product slider.  
**First issue** : In administration, i added a product slider that using **dynamic product group** and a product slider that using use **manual assignment**.  
I created a my resolver class that inherit from **ProductSliderCmsElementResolver** for loading data on storefront.  
But on Storefront only display data from **dynamic product group** , data from **manual assignment** is null.

**Second issue** : On Storefront can’t display product’s cover (I still using Product Slider). Do I need to do anything at resolver class ?

Thank everyone.
