thanks Krishna for your reply again
you right.
I rethought my design, use case, and have determined that the best way to go
about it is to send it to the action method
first then forward it to my delete view page.
This will give me more control over the item deletion request. (e.g. check
"id" correctness, if not ok then announce error.)
I'll have a same delete action method that will accommodate both call from
listItems.jsp as request for deletion and deleteItem.jsp view that will
perform the post to action for actual deletion process.
So I'm thinking something like this in words...
public ActionForward deleteItem(...) {
[if Form Bean not set as request attribute,
set it with new Item bean and set "id" parameter in bean.
Then forward to "deleteItem.jsp"]
[Otherwise if Form Bean attribute is set (in this case if deleteForm has
been posted)
then run the delete business logic process command and forward to
Success page!]
}
does this sound right to you? :)
