TableSelectDialog - paging by scroll for JSON model

Hello Experts,

I'm trying to implement F4 for my application by using TableSelectDialog.

The F4 returns ~1000 records so I don't want to get all of them at once in the client.

I've created an oData model and the paging works by design.

However, since I've only sandbox gateway I need to implement it using JSON model.

The server side is not a problem (get currentPage, number of records etc). However, I don't know how to catch the scrolling event of the TableSelectDialog  in order to fetch more records from the server.

Does someone has an example of implementing paging for TableSelectDialog for JSON model?

Regards,

Omri
