Reported on this thread: Grouping breaks when data is reloaded.

To reproduce the problem, it is necessary to:

  • perform a refresh/reload/load when a particular group is collapsed
  • expand that group and perform an additional refresh/reload
  • try to collapse the group.

At this point it will then vanish with the warning message below:
[W] XTemplate evaluation exception: Unable to get property 'get' of undefined or null reference

The simplified test case to reproduce the issue is this:

<%@ Page Language="C#" %>

<script runat="server">
    private object TestData
    {
        get
        {
            var lst = new List<object>();

            for (int index = 0; index < 15; index++)
            {
                lst.Add(new object[]
                {
                    index,
                    "Name - " + index,
                    index % 2 == 0 ? "raphael" : "saldanha"
                });
            }

            return lst;
        }
    }
</script>

This Sencha bug report appears to be the case.
https://www.sencha.com/forum/showthread.php?303384

I could not reproduce it with Ext.NET 4.1.0 (ExtJS 6.0.2).

As for v3, it is going to be fixed if we ever upgrade to ExtJS 5.1.3. Closing the issue and adding review-after-extjs-upgrade which is only related to v3. It is not needed to be reviewed for any v4 upgrades.

(I didn't unassign @DaniilVeriga, GitHub did it by itself. :)
