Hello Alessandro Strazzari,
I can recommend you to compare the code of your implementation with the code of the online demo
that you mention. What is different at your side?
There are four Load-On-Demand modes at the demo – which of them you use?
In order to help you we need to inspect the code of your implementation. Could you please provide us a simplified working page that reproduces the issue (attached to the support ticket 322935 that you have opened
Thank you in advance.
