How to eliminate an entry from an array with s2 tags

[Ezequiel Puig <e....@opodo.fr>]

Hi,
 
in my jsp, i have an array of ids and i will like to remove one of that
ids using s2 tags:
 
I have tried the following, but it doesn't work :(
<s:set name="allIDs" value="#parameters.productCode"/>

<s:set name="newID" value=""/>

<s:iterator value="#allIDs" status="stat">

    <s:set name="myID" value="top"/>

    <s:if test='%{ idToRemove != #myID }'>

        <s:set name="newID[#stat]" value="#myID"/>

    </s:if>

</s:iterator>

Does anyone know how to do it ?
 
thanks.
 
Ezequiel.

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.
