Actions can bring up Views. A modifier of the view show is the "Is Modal" modifier - that bring up the view in a modal overlay that must be closed by Ok or Cancel before continuing with other actions on the original page.

Yet a variation on the Is Modal modifier is the new "Is PopUp" modifier.

The PopUp is equal to the modal in many ways but differs from the Modal by:

• Not having the header
• Not having the ok and cancel buttons
• For allowing you to dismiss the PopUp by clicking outside the popup view

The PopUp is always submitting changes to the underlying view - and any cancel action you would like to perform must be done on the underlying (or starting) view.
