I have a Form in which Data Environment has two tables Parent and Child.
They are in parent-child relation.

In Form there are controls (textboxes and grid) for showing values of Child fields.

When I do INDEX ON childfield command for table Child and after that do thisform.refresh() all values in textboxes and grid are blank, they disapear.
But when I look in data session all values are in tables like they were before INDEX command.

I am not sure if this is a bug or what, but it's a problem for me, I can't solve it.

Help anyone?
