> Key: TAPESTRY-1112
> URL: http://issues.apache.org/jira/browse/TAPESTRY-1112
> Project: Tapestry
> Issue Type: Improvement
> Components: Core
> Reporter: Alexander Gavrilov
> Priority: Minor
> Fix For: 5.0
>
>
> Currently whe can ovveride tapesrty serives behavior via injecting
> dependencies. But sometimes services constructs another components directly
> in code and is not possible to override this dependency w/o overriding full
> selvice methods (at best) or full service class at all (at the worst). This
> service construction sould be extracted to separate overridable methods. For
> example, method getComponentConstructor of class
> org.apache.tapestry.services.impl.ComponentConstructorFactoryImpl construct
> EnhancementOperationImpl wia constructor and for using different
> EnhancementOperation implementation there is required full class overriding.
> The best approach is to put EnhancementOperation implementation instantiation
> in another method like
> protected EnhancementOperationImpl
> createEnhancementOperationImpl(IComponentSpecification specification, Class
> baseClass) {
> return new EnhancementOperationImpl(_classResolver, specification,
> baseClass, _classFactory, _log);
> }
