For init population put the data in the form bean passed into your perform method, the struts tags in your form will get the values out of the form automatically for you.
> Am I missing something? nope - you've got it sussed. Some do it your way which I suspect might be theoretically better design - it makes it easier to split the Action into 2 if required. Some (like me) do it with 1 action. I have a hidden field hard coded on the form. If this is received I know the form was submitted.
