The 3.0 stable version and dev give me an error when I create a new rules component and add a VBO condition (number of results) and when I try to load an entity object from a VBO view. This does not happen on other conditions or actions.
"An illegal choice has been detected. Please contact the site administrator."
Something breaks since the rule component does not appear in my view.
I´m running Drupal 7.17.
