I have found a strange problem with GRIDs and SET RELATIONs.

Suppose I have a table with fields KEY_A and KEY_B, which are foreign keys in TABLE_A and TABLE_B respectively. I want to set up a grid showing KEY_A, TABLE_A.NAME_A, KEY_B, TABLE_B.NAME_B, and be able to add new records with a command button.

I set all this up in the data environment of the screen, but when I add records, I get strange behaviors: either a RECORD OUT OF RANGE error message shows up, or wrong NAME_A o NAME_B values appear.

If I set up a grid with only ONE relation, the grid works fine, but when I try to work with two or more related tables, I cannot get it to work.

Does someone know what this is all about? Is there a patch, a fix or a workaround for the problem?

Thanks!
