woahh I was trying to get virtual scroll to work, and it took me so long to figure out the problem was not with my code.

Lazyloading is working correctly but as said the rows are not shown within the view, making virtual scroll unusable

This should be giving the grid a class of ui-table-virtual-table which would make the table position absolute but this class is not getting added.

I even tried adding position: absolute to tableStyleClass and tableStyle with no luck

ah you are right! It was as simple as that. When you add:

.ui-table-scrollable-body-table{
  position:absolute;
}

it seems to work. It is a nice quickfix I guess.
