Apex - Displaying a list after deserialising json - json

Question

I would like to make a http callout to import json and display the information in a visualforce page. The problem I'm having is that the json is nested and so I need to loop through the child nodes.
I have the following class derived using the json2apex application:
public class CHForm {
public class FilingHistoryItem {
public String DocumentDate;
public String FormType;
public String DocumentCategory;
public String Document;
public String DocumentDescription;
}
public FilingHistory FilingHistory;
public class FilingHistory{
public List<FilingHistoryItem> FilingHistoryItem;
}
public static CHForm parse(String json) {
return (CHForm) System.JSON.deserialize(json, CHForm.class);
}
}
In my controller class I can create a CHForm object (reponseForm) and deserialise the json into the reponseForm object using the following:
HttpResponse res = h.send(req);
String chFormJson = res.getBody();
responseForm = CHForm.parse(chFormJson);
but how do I then display a list of all FilingHistoryItem in the visualforce page? Do I need to create a list object in my controller or is there a way of directly referencing the list from the visualforce page?

I'm a bit confused by your apex, shouldn't it be :
public List<FilingHistoryItem> FilingHistory;
public class FilingHistoryItem {
public String DocumentDate;
public String FormType;
public String DocumentCategory;
public String Document;
public String DocumentDescription;
}
Then you'd be able to do:
<apex:repeat value="{!responseform.FilingHistory.}" var="item" id="theRepeat">
<apex:outputText value="{! item.DocumentDate}" /> //etc
</apex:repeat
The way you've set it up now, I think it may work like this:
<apex:repeat value="{!responseform.FilingHistory.FilingHistoryItem}" var="item" id="theRepeat">
<apex:outputText value="{! item.DocumentDate}" /> //etc
</apex:repeat
But it's a bit strange you name a list property as "...Item" and not "..Items", and nest so deeply, but maybe that's a json dependency.
