1. Create new Seam Project via New Web Seam Project wizard. Set JSF 2.0 facet version.
2. See the generated faces-config.xml:

<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
<application>
<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
...
</application>

</faces-config>

For jsf 2.0 we should not set com.sun.facelets.FaceletViewHandler. It's required only for faces-config 1.2.
