Jon,
The way it is managed is, while you paint the "delete" links in your HTML, you add a query string like this
?itemid=xyz
and then in your action class method obtain the value of this variable itemid ( obviously through form-bean)
and this is how single statement can do the work
Hope this answeres your query.

Dear All,
Trawled through the archive with no luck, but then I couldn't work out
the best search terms for this question, so.......
I'm writing a shopping basket app with the usual requirements, and using
tiles which has made things a lot less painful. However, I have this one
problem that I can't work out a nice way to solve.
On every page of the basket the contents of the basket are shown in a
panel at the bottom of the page, and against each product is a 'delete'
hyperlink. When the user clicks on this link the product should be
removed and the page refreshed to show the modified info.
My question is - how to code the logic to do the deletion of the product
in such a way that the refreshing of the page is handled in a nice way ?
I have the usual way of using an Action to populate the contexts to
render the page, and then an Action to process the users response. When
a product is removed I will have to delete the product & then redirect
the user back to the Action to populate the page all over again.
As far as I can see I have 2 options :
1. Have one Action that performs the product removal and that accepts a
URL as a parameter that then redirects the user using that URL. I will
have to place the necessary URL in the context so that when the page is
rendered the redirect URL is set correctly for wherever the user is.
Painful & not very nice - every populate Action will have to put the
correct URL for itself into the context.
2. Have a seperate Action for every single delete page so that each
instance knows where to send the user back to. Not much different from 1
& leads to a lot of Actions.
Any ideas ?
Am I missing the obvious ? For example, for 1 can I simply use the
present request URL as the URL to redirect the user to to redraw the
page ?
Jon.
