Hi , what i'm trying to do is first to load arraylist of student objects in h:datatable in the jsp, than on submit i want to get those student collection back in backing bean.
The datatable will have student information in columns containing h:inputtext. So user can edit the collection of student .
For this i did binding with HTMLDatatable in backing bean. but this gives me null pointer exception. why?
This is as follows
