title: Drupal views reset exposed filters values on change
body: <p>in my view I have 3 exposed filters based on different vocabularies. My need is to use only one filter at a time, when a value is selected in one filter the two others have to be automatically reset (to "-any-"), I googled and I only found one similar question but the answer (expose reset button) doesn't really fit my need. I suspect there must be one simple solution to this common (I guess) requirement.
  I'm using BEF but no help from this side I fear.
  Thank you for helping !
  EDIT : I put my three filters in a group using AND operator</p>
