In autoBeansFacelets, I use the ice:inputFile component, but it shows up as a
500 error, because it's throwing an exception. In this case, trying to resolve
#{FileBean.name} for the label attribute fails, because there is no FacesContext
available to the Facelets EL class LegacyValueBinding.

<ice:inputFile
  id="inputFileComponent"
  label="#{FileBean.name}"
  file="#{FileBean.file}"
  progressListener="#{ProgressBean.progress}"/>


javax.faces.el.EvaluationException: null Expression: #{FileBean.name}
FacesContext: null
