UIComponent attribute defaults are not used when bound to managed bean property
by EL, even if the managed bean property is null

Key: MYFACES-2915
URL: https://issues.apache.org/jira/browse/MYFACES-2915
Project: MyFaces Core
Issue Type: Improvement
Components: JSR-314
Affects Versions: 2.0.1
Reporter: Hanspeter Dünnenberger
As asked by Leonardo I open this issue in relation to issue
https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=1805 on mojarra to
check if MyFaces can do the same. For full description see issue above, short
description below:
Assigning a UIComponent attribute with EL expression disables the default value
handling that some attribute feature (e.g. rendered==null is the same as
rendered==true). Since EL expression never evaluates to null an expression like
rendered="#{bean.rendered} with bean.rendered=null will evaluate to False,
since for the rendered attribute the expected type for the ValueExpression is
Boolean.
The proposed change would be to use Object as expected type to allow null
evaluation from EL and convert to the really expected type later in
TagValueExpression. For details see original issue 1805 on mojarra.
