Hello,

The field is displayed even if it's content is empty ??? How can I hide it if there's no output value?

Thank you.

There is a semi-solution for this problem: http://drupal.org/node/1349904

But if you don't want to store field values in the DB, your field will be always visible, even if it empty. I am sure it's a bug in the code, but the module is almost not maintained now. :-(

It would seem that this is not a problem for fields stored in the DB because they are tested as empty/non-empty each time the field is saved (via computed_field_field_is_empty()). If nothing is saved, then Drupal knows there is nothing to display.

Fields that don't use the DB for storage don't receive this "is_empty" check. However, I think it would be possible to implement a similar check at display time within computed_field_field_formatter_view(), which is what the attached patch attempts to do.

Perhaps others could test this out.
