Problem with Refreshing the data bound text fields

Question

Folks,
First of all, this a GREAT product and I am moving my apps from Eclipse to Studio Creator. I am very impessed with it so far.
I am gone through most tutorials, but can't help resolve the problem that I am having. I have a page, that lists all the users in a table. When you click on any user, it opens up another page that lists the detail of the specific user you have clicked on. This a typical use in most web applications, right?
In the user detail page, I open it in "Read" only mode, by setting the "setReadOnly" to true for all text field components. Then users can edit it by clicking "Edit" button. Edit button just changes the "setReadOnly" to false, to allow editing. After editing, they can hit the "Save" button to save the changes. In the save button, I call this code:
public void prerender() {
        try {
            userID=getSessionBean1().getUserID();
            getSessionBean1().getWeb_userRowSetUserDetail().setObject(1,userID);
            getWeb_userDataProviderUserDetail().refresh();
            info("prerender: Refresh called");
        } catch (Exception ex) {
            error("Error in userForm.prerender():"+ex.getMessage()+ex.getStackTrace());
            log("Error in userForm.prerender():", ex);
        setReadWrite();
public String btnSave_action() {
        try {
            getWeb_userDataProviderUserDetail().commitChanges();
            getWeb_userDataProviderUserDetail().refresh();
            info("Data Provider Refreshed in SAVE");
            _readOnly=true;
            form1.discardSubmittedValues("saveVForm");
            info("User Updated New:"+userID);
        } catch (Exception ex) {
            log("Error Description", ex);
        return null;
    public String btnEdit_action() {
        try {
            _readOnly=false;
            //info("User ID Edt="+getSessionBean1().getUserID());
        } catch (Exception ex) {
            error("Error in userForm.btnEdit_action:"+ex.getMessage()+ex.getStackTrace());
            log("Error in userForm.btnEdit_action():", ex);
        return null;
    private void setReadWrite(){
        // Set read-only to true or false for all text fiels
        this.btnEdit.setVisible(_readOnly);
        this.btnSave.setVisible(!_readOnly);
        this.user_id.setReadOnly(_readOnly);
        this.user_email_client.setReadOnly(_readOnly);
        this.user_email_office.setReadOnly(_readOnly);
        this.user_fname.setReadOnly(_readOnly);
        this.user_lname.setReadOnly(_readOnly);
        this.user_id.setReadOnly(_readOnly);
        this.user_password.setReadOnly(_readOnly);
        this.user_password_conf.setReadOnly(_readOnly);
        this.user_phone_cell.setReadOnly(_readOnly);
        this.user_phone_cell_aac.setReadOnly(_readOnly);
        this.user_phone_client.setReadOnly(_readOnly);
        this.user_phone_home.setReadOnly(_readOnly);
        this.user_phone_office.setReadOnly(_readOnly);
    }When the save button is clicked, the database is updated (as I can verify by looking directly into the database), but the data-bound text fields do not display the new value. YES, I am calling refresh() on data provider? I tried to call refresh in both "preRender()" and "Save" button action event, but that did not help either.
Please note that the save button also changes the "setReadOnly" back to TRUE for all text fields. That means, users view the page in Read-Only mode after saving. (They have to click on "Edit" button again to edit it). I discovered that if I do not set the text field components in "ReadOnly" mode, then they display the updated value of the fields. But if I change setReadOnly to TRUE, then they display the old values (before the save).
Any idea what I am doing wrong here?
Thanks

Here is my experience with it. I have three text
boxes to be filled out. They are part of a virtual
form with an add button as the submit. You can fill
out the 3 and add them and a node is added to a tree
component. When you click on a node in the tree
component (the submit to another virtual form that
the 3 buttons participate in) the text fields should
be loaded with the values that they where added with.Hard to tell from this explanation, but if the text fields do not participate in a virtual form, then they are not going to get updated when an action in the virtual form happens. Not sure this is your problem. Like I say, hard to tell from this explanation.
They will not display the values though...having
nothing to do with read only. If I disable them
before hand...they display the updated values. If I
set their value at the top or bottom of prerender,
they display the change...if I set the value in an if
conditional that is hit (I have checked many times)
in prerender, they will not display the values. If I
set them in the tree handler anywhere, they will not
display the values. This is very frustrating and is
wasting tons of my time...I simply want to load the
text fields based on the tree node that was
clicked...I have messed with this for hours and it
certainly does not work.Well, setting them in the tree handler won't work because the tree handler gets called in the page instance that handles the submit and not the page instance that renders the response.
Posting your prerender code might help. Also, your action handler.
