Question

I habe a problem with my latest Liferay Portlet or rather a JSP I’m using in this portlet.
I am using a string array that contains strings which are shown on the page with a delete-button. Each of these buttons calls an actionURL to submit the selected data to another function.
Maybe it’s easier to understand what I want to do by just looking at my example code:

<c:forEach var="name" items="<%=myNames %>">    
    <liferay-portlet:actionURL name="deleteName" var="${name}">
        <liferay-portlet:param name="myName" value="${name}" />
    </liferay-portlet:actionURL>    
    <c:out value="${name}" />
    <liferay-ui:icon-delete label="<%= true %>" url="${name}"/> 
</c:forEach>

Maybe you already noticed what my problem is: the var-attribute in the actionURL has to be a string. That’s why this example doesn’t work.
My question is now: how can I cast my $name variable dynamically to set it int the actionURL and later call it with the icon?

Thank you.

<%
List<String> names = new ArrayList<String>();
names.add("me");
names.add("myself");
names.add("I");

pageContext.setAttribute("names", names);
%>

<c:forEach var="name" items="${names}">
    <portlet:actionURL var="deleteURL">
        <portlet:param name="myName" value="${name}" />
    </portlet:actionURL>

    <liferay-ui:icon-delete label="<%= true %>" url="${deleteURL}"/>
</c:forEach>

Does this work for you?
