Description

Re: ui-grid 3.0.7 (tree implementation)

I have been unable to figure out why grid.renderContainers.body.visibleRowCache does not refresh when splicing in more data ($scope.gridOptions.data) as child of a specific node in the tree (I've added a few rows, but count does not change even though I see these rows displaying within the grid).

It does set the cache to my initial data size (61 rows) but does not subsequently update as I add more data.

How does visibleRowCache work? I thought it displays exactly what is being displayed in the Tree/Grid? What am I missing, do I need to invoke something additionally to update rows in visibleRowCache?

Thanks!

Research direction: Investigate the grid render container's visibleRowCache population mechanism. Look at source files related to tree rendering, such as 'src/features/tree' or 'src/js/core/render.js'. Check issue comments for any hints about the observed behavior. Understand how data splicing triggers cache update and identify missing update call.
