Configures a custom PostApply listener class. PostApply listeners are only applied if the object was successfully stored to the database. They are useful for integrating with external systems. For example, you can use a PostApply listener to send information about a part to SAP system. This way the data won't be sent unless the data is saved successfully. It may also be used for resource cleanup. PostApply listeners require the system to cache data from the PreApply code. This caching process can affect performance.

This example shows the configuration for a custom PostApply listener:
