----------------------------------------
+1, great :)
> Processing @ResourceDependency on each component instance takes too long

> Key: MYFACES-2854
> URL: https://issues.apache.org/jira/browse/MYFACES-2854
> Project: MyFaces Core
> Issue Type: Improvement
> Components: General
> Affects Versions: 2.0.2-SNAPSHOT
> Environment: myfaces current trunk
> Reporter: Martin Kočí
> Assignee: Leonardo Uribe
> Fix For: 2.0.2-SNAPSHOT
>
> Attachments: MYFACES-2854-1.patch, MYFACES-2854-2.patch

>
> Consider custom renderer with @ResourceDependencies (and many
> @ResourceDependency here). If a view has 500 UIComponent with this custom
> renderer, ApplicationImpl._handleAnnotations process the same set of
> ResourceDependecies again and again.
> With my test scenario, VDL.buildView takes therefore 750ms. After small
> modification in ApplicationImpl _handleAnnotations it takes only 70 ms.
> The modification can be like:
> Class<?> inspectedClass = inspected.getClass();
>
> // Process annotation only if this is the first creation of
> component(renderer,validator, converter) of particular type in this
> request/response
> if (! context.getAttributes().containsKey(inspectedClass.getName()))
> {
> _handleListenerForAnnotations(context, inspected, inspectedClass,
> component, isProduction);
> _handleResourceDependencyAnnotations(context, inspectedClass,
> component, isProduction);
> // Remeber here that this class and it's dependencies are in
> viewRoot.componentResources
> context.getAttributes().put(inspectedClass.getName(),
> Boolean.TRUE);
> }
> ;
> But I'm not sure what specification says about this processing.
