I'm using the gform_pre_render filter to overwrite the choices in a poll with a list of post titles from a custom post type (i.e., vote for your favorite post). The front end dropdown works perfectly, and the correct values are recorded as entries. However, the form's poll results and results within each entry only reflect the default values for the field. Is this a bug or is there another hook I should be using? Ideally, the only percentages shown on the poll results will be the names of posts that have had votes. I'm using Gravity Forms 1.7 and the polls add-on 1.3.
