QUESTION:
Grid, grouping, LiveBindings problems.
I've created test project, which utilizes grid and FireDac TADMemTable as local data storage. There are some sample data prepared as well.
It seems that grouping and live bindings fight each other for table layout.
1) Load sample data, clicking on Load button,
2) then group on column 2 (enter 2 in numeric edit, and click Group button).
Grouping records got created OK, column 2 got hidden (right, hidden, not deleted?).
3) As soon as one tries to scroll through records, extra column re-appears automatically, seems that LiveBindings engine try to re-create column the grid was grouped on.
In addition, numeric editing in column 1 is not working somehow... The same value, entered in plain edit control under grid works fine.
Adding 'cherry on the cake', the grouping row misses the +- marks in fixed column on the left, just empty rectangle is shown.
PS. I use quick bindings, not TMS-ones, maybe that's the root of all evil.
