But there is still some problem, if I want to add a delete button after
each row, is it very difficult? Or the easier method is add a checkbox
before the listbox in class CompositePanel and then add a "delete" button
(one and only one for the HATestPanel, not per row) to the HATestPanel?
I see this forum attachment page, it has a delete link after the browse
button of each attachment row, but I have no idea how could this be
implemented in my case?
