VirtualScrolling in TreeTable with single parent and thousand of sub-nodes

[shiv]

Hi,

I am trying to get VirtualScorlling done in TreeTable, and lazy load the JSON data on scrolling. It is working fine when I have many parent nodes with sub-nodes. But for my case, I have only one parent node with thousand of sub-node and sub-sub node. When I read the JSON, Angular treats entire JSON as only one row (as all sub-nodes belong to same parent). I don't find a way to read the JSON in chunks on (lazyload) event.

I am stuck. Please let me know if more details required.
