Extjs 4.2.1 - Collapsing and Expanding grouped iitems fire the wrong events
In a grid with Grouping feature if you Collapse or Expand a group it will fire the itemadd and itemremove events of the grid view.
But actually removing and adding data to the grid store/view will not fire these events of the gridview.
Thanks for the report. I'm not seeing this.
I'm probably missing something. Can you please post a test case which reproduces the issue?

I've attached a zip file with a case test.
