More problems with commandButtons / commandLinks in datatables
We are facing a serious problem with using commandButtons and commandLinks inside datatables. Clicking on the button on start_page transitions to data_page, but clicking on the buttons on data_page does NOT transition to end_page as expected. Giving the bean a session scope fixes the problem, but that is very undesirable for our application, and we cannot understand why that's necessary.
A very simplied version is shown below. What is going on here?
