You can also extend the Selector function to be a general callback function so that item type context information can be reset as needed if the SQL session is interrupted during the execution of a process. This is particularly important in the Oracle Applications scenario when you view a notification from the Notification Details web page and attempt to launch another form that is associated with the notification. Oracle Workflow calls the selector/callback function for your item type in 'TEST_CTX' mode to test the Oracle Applications context before turning the form launch over to the Oracle Application Object Library function security system. In 'TEST_CTX' mode, the selector/callback function can perform whatever logic necessary to determine whether it is appropriate to launch the form. See: Standard API for an Item Type Selector or Callback Function.
