Get field names from joined table

[asinha_ppc]

Hi, I have a feature class joined to a standalone table and published as a map service. I have a simple JavaScript webapp.

And when I run this script, I only get the field names from the original feature class (and nothing from the joined table).

var attributes = feature.attributes;

for (var attributeName in attributes) {
  if (attributes.hasOwnProperty(attributeName)) {
    alert(attributeName + " : " + attributes[attributeName]);
  }

How do I retrieve the list and values of all the fields from the joined table?

Thanks!
