Hey,

My firm loves using this product and we just ran into a blocker issue. It seems that when we use grouping we can't collapse. And this issue is becuase we refresh teh grid every 100ms since we use cometd/web sockets to update the grid while data comes in throughout the day. With furthur investigation I found that it does collapse BUT everything becomes uncollapsed after the grid is refreshed. So if we refresh every 100ms it seems like no collapse happens. What I did as a bad solution which doesnt work well is to save everything that is hidden, refresh, then hide the rows I stored. Here is my bad solution, maybe there is a better one:
