in the dvd store example, i notice that some of the view 'code' checks for null
component values (e.g., <f:subview rendered="#{currentUser == null}">).
however, it looks like the SeamVariableResolver automatically creates a
component when resolving a name:
public Object resolveVariable(FacesContext facesContext, String name) throws
EvaluationException
{
name = name.replace('$', '.');
log.debug("resolving name: " + name);
Object component = Component.getInstance(name, true);
so how can the component value ever be null?
