I have 2 tables (let''s call it parent and child) with relations, and a GDBG bound to the child table. The child table contains a expression column (i.e. "Parent(relation).col").
When the parent table data is updating, I can see the change reflected on the grid. I can sort on the particular column.
If the child table starts to update its content, and at the same time I am sorting on the expression column, sooner or later the grid crashes with NullReferenceException.
I think it is a DataView problem, I am just wondering if anyone has a workaround?
