Instead of field.item.element, try working with the array field.item.fields and then field.item.fields[0].element.addClass.
This is from a snippet run as a Field Renderer on a table column.
// Also get the element of the Case Manager field
// (should be fields[1], the 2nd column) and highlight it also
for ( i=0; i<field.item.fields.length; i++)
{
if ( field.item.fields[i].id == “Case_Manager__r.Name” )
{
field.item.fields[i].element.addClass(“blueHighlight”);
break;
}
}
The table column is an empty UI-Only field. I assign a value inside the snippet and then render it with:
skuid.ui.getFieldRenderer(field.metadata.displaytype).read( field, value );
You might be able to read the value of a non-ui-only field from arguments[1] and then append to it. However, this page broke with Millau and we had to rebuild it. I don’t recall if the UI-Only fields were a necessity or a convenience (so three fields could be populated with one snippet).
