Hi,

It looks like the 'form passes validation' condition is being used to validate each line of data in your list view. I'm not sure if this is a correct way to go about it. Perhaps, another way to achieve this is to use the 'For all row on a List View' or 'For Selected rows on a List View' condition in conjunction with the advanced condition, the advanced condition can be setup to validate the SmartObject values (i.e. Value is not Empty).

Thanks.

I hid all the list view on the form. Set up a rule, if not empty, show the list view. Works.

If you make a rule if empty, then hide list view, does not work.
