This problem turns out to be a bug in Myfaces. More precisely org.apache.myfaces.view.facelets.tag.jsf.ComponentTagHandlerDelegate who creates and adds the components into the component tree doesn't know to assign unique IDs to the components when the tag handler is included in a c:forEach tag. In Mojarra com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl knows how to avoid this problem. Here's the inline comment found in the relevant block of code:

        // If the id is specified as a literal, and the component is being
        // repeated (by c:forEach, for example), use generated unique ids
        // after the first instance
