In a struts 2 application, in jsp I have two sections, One parent informaion and many child records against the parent. So child record when I add, I call a addRow method on action which appends a new child record object to the list. But I'm failing to retain the previous child records, it becomes the default records again.
Any idea how can I retain the unsaved child records ?
