--------------------------------------
Summary: Support Sling Validation through a new field of the Model
annotation
Key: SLING-4161
URL: https://issues.apache.org/jira/browse/SLING-4161
Project: Sling
Issue Type: Improvement
Components: Extensions
Affects Versions: Sling Models Implementation 1.0.0, Sling Models API 1.0.0
Reporter: Konrad Windszus
The current way of integrating Sling Validation (SLING-2803) with Sling Models
is to inject the validation service and then call it within a PostConstruct
method
(http://www.slideshare.net/raducotescu/apache-sling-generic-validation-framework/16).
This has the drawback that
# the {{ValidationService}} needs to be injected
# a PostConstruct needs to be implemented
# the other injections need to be marked as optional (otherwise the validation
is never triggered in case of e.g. missing required valuemap values)
Instead it would be good to support this use case with just an additional field
on the annotation {{Model}} which is named {{validate}}. By default this should
be {{false}} (to be backwards compatible), but if it is {{true}} the Sling
Validation should be called before any values are injected into the model. If
validation fails the {{ModelAdapterFactory}} should never instanciate the model
and rather return null (or throw a meaningful exception for SLING-3709).
