Crash after updating service release

Today updated to this release
Version 7 SR11
(7.11.21257.7001, 2021-09-14)
and crashes on a custom eto panel

After a while this code snippet
will reproduce the problem, was working in previous release

    treeGridView = new TreeGridView();

        treeGridView.Columns.Add(new GridColumn
            Resizable = true,
            AutoSize = true,
            HeaderText = "Load",
            DataCell = new CustomCell
                CreateCell = r =>
                    return null;


Hi @gerryark ,

It’s not clear to me what you are trying to do here. Can you explain further what you want to do?

Hi Dale

The code is a bit more complex than that, it checks for content and creates
a combo or other input control. on failure it was returning a null item.
Before the update, all was working fine, but then it was just crashing.
I did a debug and found that the crash was on null return

Well I have fixed my problem making a empty label instead of a null
