Leonardo Uribe resolved MYFACES-3830.
-------------------------------------
Resolution: Fixed
> Component created using @FacesComponent with createTag=true and
> @ResourceDependency makes initialization fail
> -------------------------------------------------------------------------------------------------------------
>
> Key: MYFACES-3830
> URL: https://issues.apache.org/jira/browse/MYFACES-3830
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-344
> Affects Versions: 2.2.0-beta
> Reporter: Leonardo Uribe
> Assignee: Leonardo Uribe
>
> Doing some tests over MyFaces Core, I found that if there is a declaration
> like this:
> @ResourceDependency(name="test1.js")
> @FacesComponent(createTag=true,
> namespace="http://myfaces.apache.org/testComponent";,
> tagName="simpleComponentA",
> value="org.apache.myfaces.view.facelets.pool.UISimpleComponentA")
> public class UISimpleComponentA extends UIComponentBase
> It throws NullPointerException in Application.createComponent. The reason is
> in FaceletsCompilerSupport there are some lines that help us to get the
> default rendererType to use it later, but when the @ResourceDependency is
> found, it is added to the current view root, which is just wrong.
> The solution is use a FacesContext wrapper and set a dummy UIViewRoot when
> this initialization step is done.
