I'm trying to use combobox inside a grid. The grid recordsource is a secondary table and the combobox shows a field from a primary table. When I leave the combobox this data is display as text. I also have a relation between both tables in Dataenvironment.

If the grid have many rows, the combobox displays differents values, deppending on the relation. This generally works, but sometimes don't.
It seems like the relation is broken (maybe when i leave the grid)and the combobox display the same value in all rows. When I click on the combobox again it shows me the correct value. Thanks
