Basic App Support for Loosely-Coupled Interactions
Basic apps created in the App Maker wizard can be either publisher or subscriber in a loosely-coupled interaction and thus can interact with custom apps in a workspace. If the app has input parameters, it defines a standard subscription topic named propertychange with a payload containing all its input parameters.
Note:  
All input parameters for an app are available for wiring interactions. Settings for the editability and visibility of input parameters in a basic app do not apply.
Basic apps publish topics only if the views selected for that app have events. See Views for Mashups and Mashables for links to each built-in MashZone NextGen view with information on the events they support.
