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:
{{
