Er, no. But you probably didn't mean ESQL anyway.
You need to do it as you did it before: retrieve the value, add a new
element to it and then store it again.

Would translate to
<xsp:logic>
Object items = <xsp-session:get-attribute name="cart.items"/>;
if (items == null) items = new Vector(10,5);
((Vector) items).add(<xsp-request:get-parameter name="item"/>);
request.getSession().setAttribute(items);
// logicsheet only supports setting Strings objects :-(
// thus do it manually.
</xsp:logic>
