DataModel dependent of values

Question

Hi,
I have a jsf page using an inputText storing a value (such as a firstName), and a dataTable using a dataModel.
The data come from the DB with the request (EJBQL):
select p from Person p where p.firstName=:firstName
I don't wnat to store the dataModel into the session, so in the APPLY_REQUEST_VALUES phase, the model is built by the getModel method:
DataModel getModel() {
  if( _model == null ) {
    // Get the value of "firstName"
    // Create the model
    // execute the request
    // set the resulting list into the model
  return _model;
}But ... the value of "firstName" is null, not yet set.
Any solution?
How can I restore dynamically the dataModel using a value stored in the same page?
Tks !

Sabenah,
this question is best answered in one of the Portal forums on OTN. I can imagine that Portal has a way to dynamically populate Javascript.
