In-App-Purchasing with Soomla problem

Hi there,

I am trying to implement an inApp purchasing system into my game but it is not working. I watched the videos on youtube and compared my code to the example project.

my problem: the example object "no ads" works fine, but all the others don't. (lists only have the example object) they are simply not returned in the get function...

here is the code for the nonconsumables:

 public static string NO_ADS_NONCONS_PRODUCT_ID = "android.test.purchased";
         public static string Hat_NONCONS_PRODUCT_ID = "test_object_001";
 
         public static NonConsumableItem NO_ADS_NONCONS = new NonConsumableItem(
             "No Ads",
             "Test Purchase",
             "ID_01",
             new PurchaseWithMarket ( new MarketItem(NO_ADS_NONCONS_PRODUCT_ID, MarketItem.Consumable.NONCONSUMABLE, 0.99))
             );
 
        //Hat
         public static NonConsumableItem Hat_NONCONS = new NonConsumableItem(
             "Hat",
             "Test Purchase",
             "ID_02",
             new PurchaseWithMarket(new MarketItem(Hat_NONCONS_PRODUCT_ID, MarketItem.Consumable.NONCONSUMABLE, 0.99))
             );
 
         public NonConsumableItem[] GetNonConsumableItems()
         {
             return new NonConsumableItem[] { NO_ADS_NONCONS, Hat_NONCONS };
         }

the strange thing is, that GetNonConsumableItems() returns an array of length 1. I already used a lot of different IDs for testing.

thanks for your help!
