Hi Henry, I’ve seen this behavior when building the model fails (because of a failed injection or an exception in @PostConstruct ) and then sightly falls back to the regular java pojo Use provider, which does not support injection (so all fields are null). Check your logs or debug to see if this is the case.
If that is the problem I recommend you to install org.apache.sling.scripting.sightly.models.provider, which uses the ModelFactory service instead of adaptTo to build Sling models. This will make errors more apparent and you won’t get a fallback to the pojo provider.
