I am re-creating the selection tool within our own mashup and I'm trying to use the Selection API. Currently, we have our items using an expression in the "Field" and a title in the "Title"

We've made sure that "Show Titles" was on, but I'm not able to get the actual "title" out of the selection object. All I get in the fieldName is the "field" which is an expression.
Is there any way I can get the title from the object? I can't find it anywhere.
