Adding Components And There Value Bindings Programmatically

Question

Dear Friends ,
In One of assignment I have requirement of creating JSF Components
and There Value Bindings Programmatically
on valuechange event of a SelectOneListBox I need to create some componenet and add them to a panelGrid...up to this it's okay I have already achieved this goal but my next big challenge is creating value bindings programmatically for those components...
suppose I have created a textbox component in which user has to insert some text and that text I want to store in a database ..
how to do that...?

Answer 1

tht's simplest way ..I know but suppose
my code is like this....
public void buildComponenets(int selectedId) {
ArrayList arrList = new ArrayList();
arrList = objABC.GetDocumentParameter(selectedId);
Iterator iterate = arrList.iterator();
HtmlInputText htmlText;
HtmlSelectBooleanCheckbox htmlSelect;
HtmlOutputLabel htmlLabel;
HtmlMessage htmlMess;
int i = 1;
ABC objABC= new ABC();
while(iterate.hasNext())
objABC = (ABC)iterate.next();
String compType = objABC.getControlName();
if(compType.equals("TextBox"))
htmlText = new HtmlInputText();
htmlLabel=new HtmlOutputLabel();
htmlMess = new HtmlMessage();
htmlLabel.setValue(objABC.getLabelName());
htmlLabel.setId("lble"+i);
htmlText.setId("txt"+i);
htmlText.setImmediate(true);
htmlMess.setId("message"+i);
htmlMess.setFor("txt"+i);
htmlText.setRequired(objABC.isValidationRequired());
if(cotrolsPan.getChildren().contains(htmlText))
cotrolsPan.getChildren().remove(htmlText);
cotrolsPan.getChildren().add(htmlLabel);
cotrolsPan.getChildren().add(htmlText);
cotrolsPan.getChildren().add(htmlMess);
if(compType.equals("CheckBox"))
htmlSelect = new HtmlSelectBooleanCheckbox();
htmlLabel=new HtmlOutputLabel();
htmlMess = new HtmlMessage();
htmlLabel.setValue(objABC.getLabelName());
htmlLabel.setId("lble"+i);
htmlLabel.setValue(objABC.getLabelName());
htmlLabel.setId("lble"+i);
htmlSelect.setId("check"+i);
htmlSelect.setImmediate(true);
htmlMess.setId("message"+i);
htmlMess.setFor("check"+i);
htmlSelect.setRequired(objABC.isValidationRequired());
if(cotrolsPan.getChildren().contains(htmlSelect))
cotrolsPan.getChildren().remove(htmlSelect);
cotrolsPan.getChildren().add(htmlLabel);
cotrolsPan.getChildren().add(htmlSelect);
cotrolsPan.getChildren().add(htmlMess);
i++;
now How to create value bindings for these components
