Hi Dave, Thanks for your reponse. Anyway, I will try to convince you ;)
Some background: i have a page where a list of products are shown. In that page there is a button to compare products. What the button does is collect all the selected product's id and call an action: CompareProducts.do?productID=111&productID=222 etc. As the product selection is done by the user, the complete url is created with javascript :(. Consequently, the action CompareProducts has an array like that: String[] productID. So, when the action returns the page, i can access the array productID. What i want to do is to put an button in the comparation page that allows the user to deselect a product. So, i need to call the action CompareProducts with all the ids (productID) removing the product's id that has been deselected. And i want to do that with s2 tags and not with javascript. Well, i hope it's a little bit more clear.

Depending on the underlying collection type you might get an exception. You're not removing anything in the above code anyway, you're replacing a value. You're also using the "status" value like it's an index, but it's not [1]. But why? You'd have to work hard to convince me that the JSP is the place to do something like that.
