Anyone has observed this as well?
Is this expected behavior?
I understood the importance of giving a formname when you're dealing with
two grids on one single page.
This however concerns one single grid per page in which case I believe the
formname is not required.
It looks however that the link associated to the redirect after submitting
a form is influenced by using the browser's back-button in the case when no
formname paramater is used in the grid.
Best regards,
Tom.
