Hi All I have list of module object. I want to show it to user and user can edit it and can save it also. In module object three members are there 1 String moduleName 2.boolean readFlag 3. writFlag.

The bean i am using is in Request Scop i don't want to use any other scop. My problem is setterOfThatList is not called when update button is clicked. Where as on the same page i used another inputText, setter of the variable which is connected to this inputText is called.

What you want doesn't count. Sometimes life is cruel. Computers doubly so. If you use a dataTable, you need a tableModel that can survive over multiple requests. Otherwise, a new model will be created and destroyed on each request and the context won't be valid for you.

If you're using JSF2, you can use ViewScope and that will construct a short-term session object that will automatically be purged when you go to a different view. For JSF1, you have to use session scope.

An IDE is no substitute for an Intelligent Developer.
I agree. Here's the link:
