Hello - this may be a simple question - I'm new to struts and have been figuring out ways to do what I want, but I'm afraid that there are often better ways to do them using struts.
My current problem is as follows:
I have a form bean which contains a Collection of items. I print out the list of items, each with a checkbox to delete them (essentially the same idea as a shopping cart with 'remove from cart' checkboxes). So the user can check n boxes, and hit the delete button which submits the form with the appropriate parameter.
The action class actually does the work of deleting the items (the mechanics are unimportant). I simply want the resulting page to show the list of items, minus the ones that were just deleted. However it doesn't do this until I refresh the page.
I've tried using forwards in struts_config.xml file (i.e. returning mapping.findForward("delete_success") from the execute() method in my Action class after the deletion is successful), but I want the page to which I'm forwarded to to include the original page (list of items). It's never up to date until I refresh. I can confirm that the items are deleted.
I'm not sure if this is some caching problem or a simple struts thing that I'm missing.
I assume this is a common task, as every shopping cart system must work this way.
Thanks for any advice.

you have a /cart/view.do (or something like that) to present the cart initially correct? in your action mapping for the cart update action then forward it to that /cart/view.do. ex:
