Hide empty fields on a form

[gustavo1]

Hi all,
I'm trying to do something that I don't know if possible, here is what I was requested:
We have a table with a lot of fields and those fields will be populated through a Record Producer, the table will have as well table list and a form, in the form I need to show only the populated fields, those ones that are empty should be hidden.
We will never know what fields will be empty so I was wondering if possible, if so how can I get it?
Thanks in advance for the advices.

Below is a generic loop-over-all variables on the catalog form. This combined with the logic posted earlier should get you the functionality you need without having to manually type 90+ conditions.

function onLoad() {
     try {
          var getFields = document.getElementById('variable_map').getElementsByTagName('item');
          for(var i = 0; i < getFields.length; i++)
         {
                var field= getFields<i>;
                g_form.setDisplay('variables.' + field.getAttribute('qname').toString(), false);
          }
     } catch(err) {}
}

This is really old, and I'm not sure I'll get a response here, but I did exactly what is in the article but it doesn't work for me. I did it on the Task table (not sc_task, just task). The business rule first barks at me saying that I'm creating a global variable vars and need it to be "var vars". With or without that change, it still does not seem to hide any empty fields. Any clues?
