BalusC,
thanks for ur reply..
Let me reframe my question..
here is my code snippet..
// bean
private ArrayList<MyVO> myList;
// setter and getter methods for myList......
ArrayList<MyVO> getRows(){
resultFromDB=getMyRows();// call getMyRows() DAO method for results
this.myList=resultsFromDB;
return resultFromDB;
In the jsp and displaying all the rows using<h:datatable id="someId" value="#{someBean.rows}"
so far good.
In this page i have one submit button which will call confirm() of my managed bean.
In the confirm() i need to get all the rows. i.e; i need to get the myList.
I dont want to call the getRows() method again(since it is DB hit)
But myList is empty in my confirm method.
my managed bean is in request scope.
if i change it to session it is working.but i need request scope only.
I tried with <t:saveState value="#{someBean}" /> but no luck..
Later i have taken HtmlDataTable reference with setter and getters in the bean and bind this reference in <h:datatable>.
and tried to disply the htmlDataTable rowCount...
then im getting NotSerializableException though my bean is implementing Serializable interface..
Please give some suggestion in this
thanks....
