Hi... I guess I don't understand.
When you say fix is scheduled for RC2 what do you mean. Have you implemented the fix
already or you plan too.
What do you mean by "it will now work if trying to use "tableId.property" in the body
of the column"? Do you mean RC2 will now work or my code will now work? What do you
mean tableId.property? Can you send me an examples.
I tried this in both jetty jetty-4.2.22 and atg dynamo 5.1.1 and in both containers it
RC2 as it exists today it doesn't work for my example. (With my patch it does work)
Both containers are > JSP 1.1 compliant. So once again I am at a loss for what you
mean. Please clarify...

Description:
If I pass id in as <%= string %> value I get classcast exception
The code below with varying name also doesn't work. I sent this also to you guys
because my mail in the past hasn't got onto forum.
Thanks,
Garry
Here is an example of the problem (below is a workaround but you probably have better
one):
<%@ taglib uri="http://displaytag.sf.net"; prefix="display" %>
<%@ page import="java.util.List" %>
<%@ page import="java.util.ArrayList" %>
<html>
<body>
test
<%!
public class ValueBean {
public ValueBean(String value) {
this.value=value;
}
private String value;
public String getValue() {
return this.value;
}
}
%>
<%
List theList = new ArrayList();
theList.add(new ValueBean("1"));
theList.add(new ValueBean("2"));
theList.add(new ValueBean("3"));
for (int i=0;i<3;i++) {
request.setAttribute("row" + String.valueOf(i),new ArrayList(theList));
%>
<display:table class="disp"
id="row"
name="<%= "row" + String.valueOf(i) %>"
sort="list" >
<display:column property="value" sortable="true"/>
</display:table>
<% } %>
</body>
</html>
Workaround:
have anonther attribute called tableId. I'm using reflection code for visibility
issues.
