> Key: MYFACES-3219
> URL: https://issues.apache.org/jira/browse/MYFACES-3219
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Reporter: Leonardo Uribe
> Assignee: Leonardo Uribe
> Fix For: 2.0.8, 2.1.2

> Suppose this example:
> <testComposite:compositeRefVE value="success">
> </testComposite:compositeRefVE>
> compositeRefVE.xhtml
> <composite:interface>
> <composite:attribute name="value"/>
> </composite:interface>
> <composite:implementation>
> <testComposite:compositeRefVE2>
> <p>Some text: <h:outputText value="#{cc.attrs.value}"/> there.</p>
> </testComposite:compositeRefVE2>
> </composite:implementation>
> compositeRefVE2.xhtml
> <composite:interface>
> </composite:interface>
> <composite:implementation>
> <composite:insertChildren/>
> </composite:implementation>
> It works, everything is ok in this case. The final output is "Some text:
> success there.". But now change compositeRefVE.xhtml to this:
> <composite:interface>
> <composite:attribute name="value"/>
> </composite:interface>
> <composite:implementation>
> <testComposite:compositeRefVE2>
> <p>Some text: #{cc.attrs.value} there.</p>
> </testComposite:compositeRefVE2>
> </composite:implementation>
> It should do the same, but it does not work, because #{cc.attrs.value} is
> resolved to null. Why? There are two reasons:
> 1. When the markup is executed, the current component on the stack is the
> inner one (compositeRefVE2), and it should be the outer one. This means the
> inner component must be pop and push. We didn't notice the effect in the
> other case, because Location object is used there to detect the current
> composite component.
> 2. If #{cc} is used, the expression should be wrapped using
> LocationValueExpression, like on TagAttributeImpl
> Additionally, I saw we are not caching inline EL expressions, so this is a
> good oportunity to do it.
