Out of the box the date field can accept a 'from' and 'to' date parameters and the 'to' date field will auto update when the 'from' field changes. As work has progressed on my site the field no longer automatically updates. Any idea as to why this would happen?
I recreated the date field settings on a clean install of drupal. I installed/enabled views, ctools, and the date api. I enabled the date popup widget and created a dummy content type. The popup and textfield widgets for the date field do NOT auto update but the select list does. I guess this is how it is designed. Back to the drawing board on this one. the popup module could possibly be modified to allow auto updating.
