Flex with Cairngorm 2 - Popups Strategy

This post is a brief summary how we use Cairngorm 2 methodology for popups in Flex applications in the IT shop I work at:

• Three files are created for each popup:
  
  • popup view
  • Cairngorm event to initiate showing of the popup
  • Cairngorm command to actually show the popup using PopupManager

• Any data that needs to be passed to the popup is attached to the event.

• When user closes the popup, the popup view simply removes itself from PopupManager.

• The results of the popup, if any, are updated (can be done via data binding) in the ModelLocator, to which other controlls are bound as well, if needed.
