logic:iterate displaying blanks
hi,
I had a good search on the user group and could not find any answer for this
one. I have a DispatchAction class, called ShowLogsAction that goes away and
returns a list of LogItem items. All the properties on LogItem are public eg
public String auditDate
ShowLogsAction
<snippet>
System.out.println("Entering ShowLogAction");
ValueListHandler listHandler = new LogListHandler();
DynaActionForm logForm = (DynaActionForm) form;
List logs = listHandler.getNextElements(20);
ArrayList logList = new ArrayList();
for(Iterator i = logs.iterator(); i.hasNext();){
LogItem log = (LogItem) i.next();
System.out.println("action date=" + log.auditDate);
logList.add(log);
}
logForm.set("logList", logList);
</snippet>
I have iterated through the Collection again in the action just to make sure
the values are being returned. Everything looks OK to this point.
In my jsp, showLogs.jsp, I then iterate over the Collection and print the
date and and userNaem properties of the LogItem in the Collection. This is
done as so.
showLogs.jsp
<snippet>
<% String forward = "/showLogs"; %>
<html:form action="<%= forward %>" >
<TABLE border="1">
<TBODY>
<logic:iterate id="logs" name="logsForm" property="logList"
scope="request"
type="com.cuscal.payments.bpay.enquiry.LogItem">
<TR>
<TD>auditDate= <bean:write name="logs"
property="auditDate" /> </TD>
<TD>user name= <bean:write name="logs"
property="userName" /> </TD>
</TR>
</logic:iterate>
</TBODY>
</TABLE>
</html:form>
</snippet>
While I get 20 rows back they are all blank. This is the result.
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
auditDate= user name=
Obviously this has caused me hours of amusement. Can anyone think why this
would be producing such a result? All suggestions gratefully appreciated.

I think you want to do a
html:form action="/showLogs.do" ?
also, check to see what your html source is for this
form line and verify that it is using the "name"
element from your struts-config.
