Page is not rendering as per requirement request

Question

Hi All,
Basically Here is the scenario.
Based on selectoin of particular service item from combo box(dropdown list), We are creating the JSF controls dynamically on new page for further process.
We are maintaining the controls information in database that need to be created dynamically and rendered for each service.
And I am able to create the controls dynamically and able to place them on page perfectly.
Until here everything looks ok for me.
But main problem I have identified is when I go for new request, I am getting the same old page when I select the other service.
Initially I though this could be a problem of caching and I have placed meta info in order to expire the page. But that was no use.
So I logged all the data that is coming from database and logged the information where I have created the controls dynamically..
What I have identified is I am getting the right data on paricular service selection and even I am able to see that methods execution is correct. I was stunned and not able to understand why the JSF is not able to show the controls.
So I searched the JavaDoc for solution. I though I could use FacesContext.release() method. But that does not help me. Even I tried to clear the parent objects using gridpanel1.getChildren().clear(). Even that does not supported me :(
In order to understand my problem, here I am pating the code.
Please help me why the hell my page is not rendering
Below is code in constructor
javax.faces.context.ExternalContext ec = context.getExternalContext();
            javax.servlet.http.HttpServletRequest request=(javax.servlet.http.HttpServletRequest)ec.getRequest();
            String service=request.getParameter("form1:cmbServices");
            int serviceid=-1;
            if(service!=null) {
                serviceid=Integer.parseInt(service);
            gridPanel1.getChildren().clear();
            controls =getControls(serviceid);
            HtmlControl[] controlArray =controls.getHtmlControls();
            //log(controlArray.length+" Length");
            for (int i =0;i<controlArray.length;i++) {
                HtmlControl control =controlArray;
//log(control+" Control");
//log(controlArray.length+" Length");
if (control.isRadio()) {
addRadio(control);
//log("Entered here in adding radio");
else if (control.isCheckBox()) {
addCheckBox(control);
//log("Entered here in adding checkbox");
else if (control.isTextBox()) {
addTextBox(control);
//log("Entered here in adding textbox");
here is the code for dynamic creation of controls
private void addRadio(HtmlControl control) {
        HtmlPanelGrid gridPanel = new HtmlPanelGrid();
        UIComponent parent = gridPanel1;
        HtmlOutputText outputText = new HtmlOutputText();

        String desc =control.getDescription();
        desc=desc.replaceAll(" ", "_");
        outputText.setId(desc);
        outputText.setStyleClass("bodyText");
        HtmlSelectOneRadio radio = new HtmlSelectOneRadio();
        radio.setBorder(0);
        radio.setLayout("pageDirection");
        //radio.setId("Radio_"+control.getId());
        radio.setId(control.getName()+"__"+control.getId());
        UISelectItems items = new UISelectItems();
        Radio objRadio =(Radio)control;
        //  vectDefaultSelectItemsArray
        DefaultSelectItemsArray objArray =new DefaultSelectItemsArray();
        vectDefaultSelectItemsArray.add(objArray);
        //log("vectDefaultSelectItemsArray :"+vectDefaultSelectItemsArray.size());
        arrays=(DefaultSelectItemsArray[])vectDefaultSelectItemsArray.toArray(new DefaultSelectItemsArray[vectDefaultSelectItemsArray.size()]);
        int size =arrays.length;
        arrays[size - 1].clear();
        for (int i =0;i<objRadio.getValues().size();i++) {
            arrays[size - 1].add(new SelectItem(objRadio.getValues().get(i)+"",""+objRadio.getTexts().get(i)));
        // array.setItems(new String[] {"Yes","No" });
        items.setValueBinding("value",getValueBinding("#{consumer$jobInfo.arrays["+(size-1)+"]}"));
        radio.setStyleClass("bodyText");
        radio.getChildren().add(items);
        gridPanel.getChildren().add(outputText);
        gridPanel.getChildren().add(radio);

        String desc =control.getDescription();
        desc=desc.replaceAll(" ", "_");
        outputText.setId(desc);
        outputText.setStyleClass("bodyText");
        HtmlInputText textField = new HtmlInputText();
        //  textField.setId("textField_"+control.getId());
        textField.setId(control.getName()+"__"+control.getId());
        HtmlOutputText outputText1 = new HtmlOutputText();
        outputText1.setValue(" ");
        outputText1.setStyleClass("bodyText");
        textField.setStyleClass("frmObjects");
        gridPanel.setColumns(3);
        gridPanel.getChildren().add(outputText);
        gridPanel.getChildren().add(outputText1);
        gridPanel.getChildren().add(textField);
        parent.getChildren().add(gridPanel);
here is my after render response method
protected void afterRenderResponse() {
        //job_selection_templateRowSet.close();
        jiya_html_controlRowSet.close();
        FacesContext.getCurrentInstance().release();
here is my getValueBinding method
private ValueBinding getValueBinding(String expression) {
        return     FacesContext.getCurrentInstance().getApplication().createValueBinding(expression);
    }Thanks

Hi,
You can try the following to debug and provide us more details.
1. I am assuming you are trying to navigate by using a commandLink/Command Button ? If so, is the action handler for the command getting called ?
2. Do you have input components in the page with Validators/converters attached to them ? If so, you may not watch for validation/conversion errors. If there are errors, the same page will be redisplayed. In that case you would need to associate message component to get more details on what went wrong.
3. Have you set up the necessary navigation rules to navigate to the right page ?
4. When you are adding components programatically, its better to assign explicit id's to your components, to avoid any unexpected behavior.
Hope this helps.
