NullPointerException in UIInputContainer when used with h:selectBooleanCheckbox
-------------------------------------------------------------------------------

                 Key: SEAMFACES-160
                 URL: https://issues.jboss.org/browse/SEAMFACES-160
             Project: Seam Faces
          Issue Type: Bug
          Components: UI Components
    Affects Versions: 3.0.1
         Environment: JBoss AS 6
            Reporter: Alt Avatar


I'm using the composite component definition from the input.xhtml in the Seam-Booking demo. When used with an <h:selectBooleanCheckbox/> this produces a NullPointerException in UIInputContainer.java

View template:

{{
<x:input label="Rememberme">
   <h:selectBooleanCheckbox value="#{login.remember}" />
</x:input>
}}


Composite component definition:
