I'm using Better Exposed Filters to enable datepickers for exposed date fields on my View. It's great, except that my view displays nodes via a taxonomy relationship. If I try to filter by node creation date, I don't get any Better Exposed Filters options. However, if I choose a date field that doesn't use a relationship (even if it doesn't exist on the term and therefore doesn't work), I get all the Better Exposed Filters options.
How can I best go about putting a popup datepicker on my exposed filter that uses a relationship?
