How does Drupal Views decide between multiple displays with the same path

Question

I need to have a Views that is different for different roles. But, I don't know what will happen when a customer meets the requirements for all the displays for that View. Which display will she see?

Answer 1

If you're referring to the display within the views: each view display has a position and the displays are loaded according to that position in an ascending sort. So if you create a page display (which may get a position of 2 since the Default display typically has a position of 1) and then create another page display after that, the next page display may get a position of 3. The customer will be exposed to the position it reaches first (2, provided that they have met the criteria).

If you're referring to the views themselves: views are loaded in order of their view id (vid). The customer will be exposed to the first one loaded.
