How to get the Dynamic UI component value from JSFF page to any managedbean

Question

HI ,
We have list of bean objects in jSF page we are iterating the list of bean using the forEach loop and displaying the value into Input type text (UI component) value filed .
If we try to get the UI component value in Managed bean we are not getting the dynamic values .
The below piece of code used to retrieve the dynamic values from the JSF page doesn't have any form :
UIComponent component = null;
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext != null) {
UIComponent root = facesContext.getViewRoot();
component = findComponent(root, componentId);
then component type casting to the based on UI component which we trying to access and getting the value as " NULL " ..Please let me know how to get the dynamic values form the JSF ?
Please let me know if any other approach or any changes required on above ?
Thanks

Hi,
the root problem is this
<h:inputText id="it3" value="#{familyList.ctn}" />
<tr:commandButton text="Save" id="cb3"Note how each row writes to the same managed bean property, thus showing the same data. Instead your managed bean should expose a HashMap property that you then apply values to using a key/value pair. The key could be the ID of the field, which then you also should dynamically define e.g. cb<rowIndx>. The command button could then have a f:attribute assigned that has the row HahMap key as a value. This way you truly create value instances for the object
