-------------------------------------
Summary: Required fields validation
Key: SLING-3679
URL: https://issues.apache.org/jira/browse/SLING-3679
Project: Sling
Issue Type: Improvement
Components: Extensions
Affects Versions: Sling Models Implementation 1.0.4
Reporter: Krystian Panek
Fix For: Sling Models Implementation 1.0.6
Currently if some field cannot be injected (and it is not annotated with
@Optional), model adapter factory returns null. However fact that some field
has null and all other are properly injected is acceptable in my context.
Proposal:
* model adapter factory does not return null if not all required fields are
injected,
* result of requirement validation is serviced as for example:
** injecting it to some extra annotated field: @Valid boolean valid; (with
default false),
** passing bool parameter in @PostConstruct callback, for example 'valid' (true
if all required field are injected, false otherwise),
* behave current behavior, new available only with extra model class
annotation, for example @NotNull .
