Rivka,
listIndex is necessary for displaying the information on the page, right?
What's wrong with putting it the form bean. That is what the form bean is
for. Your other options are going to be a lot messier.

Hi Richard
Yes I can do that - but the problem is that 'listIndex' does not
logically belong to the Student ActionForm - it is more an external
info.

Can you set the listIndex as an attribute of your form
in the EditStudentAction? You can then retrieve it as
part of your formBean.
