How to programmatically initialize field in ADF Creation Form

Question

I'm using JDEV 10.1.3.2, ADF BC. The task sounds simple:
1. Create an ADF Creation Form by pulling in a VO (backed by EO) from Data Control.
2. Initialize one of the required fields in a backing bean from processScope.
3. User sets other fields via GUI.
4. Save the new record in the database (Commit).
The problem is how to do step 2? The processScope variable is being retrieved properly, but I have not been able to set the required field so that the user does not have to enter this field. I have an action on the Save button as follows:
    public String commandButton_action() {
        String psnetid = null;
        BindingContainer bc = getBindings();
        AdfFacesContext afContext = AdfFacesContext.getCurrentInstance();
        psnetid = afContext.getProcessScope().get("netid").toString();
//Need to set Netid field in VO to psnetid here
        OperationBinding operationBinding =
            bc.getOperationBinding("Commit");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;
    }Can anyone shed some light on this?
Thanks.

This is outside of the backing bean, but you may try it:
modify the getter on the entity impl class (if you are using ADF BC) to set a default value
This example is to set a default status id on the field.
public class <EntityName>Impl extends EntityImpl {
public static final int STATUSINTLID = 1; //first column name on the entity
public Number getStatusIntlId() {
Object intlId = getAttributeInternal(STATUSINTLID);
if (intlId == null){
int intValue;
intValue = <get value from somewhere code>;
Number defaultValue = new Number(intValue);
if (defaultValue != null){
this.setStatusIntlId(defaultValue);
return (Number)getAttributeInternal(WATERDRAWSTATUSINTLID);
