The scenarios and slots you design are only effective if the content in ATG Service Center refreshes often enough. For either active or passive slots, refreshing the offer management panel is going to ensure that the slots are displaying the most relevant content for the current situation. An active slot calls for content on its own, but a passive slot is filled by some other action or behavior. To ensure the panels get refreshed and update the passive slots in a timely manner a special event, called SlotItemsFilledMessage, is fired when a passive slot is filled by the Add Item to Slot action. This event is really only necessary when using Add Item to Slot or Add Item to Slot for Customer for scenarios delivering content to ATG Service Center. The SlotItemsFilledMessage event is what helps control the panel refresh behavior to keep the content in the panel current.
You can configure whether this message event is fired by setting it to True or False. The setting is found in this properties file:
/atg/scenario/configuration/SlotActionConfiguration
The property to configure is fireSlotItemsFilledMessage.
For ATG Service, the fireSlotItemsFilledMessage property is set to TRUE by default (the event will fire upon the Add Items to Slot action). It is not advised to set this property to FALSE for use in ATG Service because this event is what ensures that the panel refreshes and retrieves new content as often as necessary. Firing this event ensures that the content in the panels never gets stale.
