When activating FixedFooters and trying to edit a cell using the TAdvEdit component and not the Gride standard, generic errors are generated, when removing FixedFooters the edition works correctly.
Do you have any example using FixedFooters totalization in DBAdvGrid?

In this image it is possible to visualize the editing attempt working with FixedFooters
The error when editing the last line of the grid.
I cannot see a problem.
Added TAdvEdit based editing on column 4 in ADOEditing demo that has floating footer active.
