Initializing backing bean

Question

I've found here an answer to a question how to initialize backing bean with get request with parameter:
http://localhost/details.faces?id=1231
create an BackingBean for your details.jsp
set its scope to "request"
in Construktor you do something like this:
public BackingBean(){  String param = (String) FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("id");// pass 'param' into SQL or something other.//result of that could be the value of backingbeans properties
if you have SQL, i recommend to use <h:dataTable> in jsp-file,
that could use a resultset directly for displaying.
Now, I have a backing bean with components in it. I see in book that I shouldn't set components values, rather let to retrieve null value and then let a call setValue. Let's say that I want to initilaize component in backing bean consructor with a value that I retrieve form database basing on id. Can I create this component by my self ? I know that this in not a good practice, but that is what I want to do.
