                 Key: JBSEAM-4261

Seam component:

@Name("test")
public class Wrapper {
    @Unwrap
    public String getAString() {
        return null;
    }
}

JSF page:

<html>
<head xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html">
    <title>Unwrap test</title>
</head>
<body>
#{empty test ? 'test is null' : test.class.name}
</body>
</html> 

 Outputs
