Hi all Carsten started to review the Sightly Engine API in SLING-4275 [1]. Since this issue covers 4 topics, I think it would be best to quickly discuss these topic in separate threads.
#2 RuntimeExtension and ExtensionInstance Currently the RuntimeExtension is a service and called to return an ExtensionInstance. For each evaluation of a Sightly Template an ExtensionInstance is created. The downside of this is a double indirection: Not the RuntimeExtension itself is used. Rather the RuntimeExtension is a factory of ExtensionInstance objects. The upside is that these ExtensionInstances can hold instance data for the duration of the Sightly template evaluation. Question is whether there actually is a use case for such instance data, which could not be held in bindings and whether it would be possible for RuntimeExtensions to implement such instance data in different ways. WDYT ? Regards Felix [1] https://issues.apache.org/jira/browse/SLING-4275
