Hi Jun,

I fully understand the troubles you are facing - configuring an endless scrolling listview has several non-trivial aspects (like the datasource paging for example).

As you have stated in your last reply, the ListView expects that the correct item amount will be returned from the server. Of course, if you have a total of 20 items, the service will return 20, even if page size is set to 30. The total amount of the items available should be configured through the schema.total datasource configuration option.

Regards,
Petyo
