Hi Volker,
I tried this but I just get null.
Do you have further ideas?
Thanks,

Hi Rudi,
you need the facesContext:
FacesContext facesContext = FacesContext.getCurrentInstance();
try either
app.getVariableResolver().resolveVariable(facesContext, "person");
without the '#{' and '}'
or
app.createValueBinding("#{person}").getValue(facesContext);
Regards,
Volker
