Select multiple values in a list box

[Anonymous]

Hello,

Could someone help me with the following situation?

I have a list box with products A, B, C; when I select A in the second list box I can see values 1, 2.

The problem is when I select A, B in the second I have the values 1, 2, 3 (so far so good), but if I try to select a value from the second list box all the values disappear and in the first one I can see only the corresponding value checked, the other one is unchecked.

Any ideas?

Thanks

It will be good if you share sample application to validate it.Other scenario might be 2 is not associated with B.
