How to set the content of a RichTextItem field in a Notes document?

This one seems like it should be simple enough. I'm writing a Notes Agent in Java; it calculates a fairly large amount of numeric data (a 6400-entry array of doubles) that I want to store in an existing document, updating a field. Because of Notes' field limitations, I figured I needed to use a RichText field to do that. (My initial attempt to write to a multi-value Number field resulted in it failing to save somewhere between an array of size 4000 and 5000.) It's not clear to me how one stores that value in a RichTextItem, though. All my attempts have failed. In one case, using doc.replaceItemValue(), it seemed to convert the item to a Text List. Getting the item, casting it to a RichTextItem, and calling setValues() or setValueString() doesn't seem to do anything. This shouldn't be this hard! Any pointers?

(Alternately: Any better suggestion for how to store my array in a document in the database?)

Thanks, Reid

As for the question of "better" solution. I've recently written some code where I serialize/deserialize Java objects as JSON strings. This way they are well readable and easily restorable. I guess for the plain array it's a little problem. Especially if you do not want to restore it and have not interest to look at it (well, but probably it should be one or other :-)

And yes, you have to store it in the rich text anyway. Alternative you might write a text document and attach it in the RT field (again RT :-). Pretty usual scenario and easy to do.

Finally you could store data as database objects, but I guess from Java you do not really have access to do it. And it does not seem to be in any way better.

You can bypass the Notes' field limitations. You can flag your item as «contains non-summary data» by using the NotesItem.IsSummary property. You need to set this property to false. But remember, you cannot use this item in views and folders.
Here is example:

Vector vector = new Vector();

for (int index = 0; index<6400;index++)
    vector.addElement(new Double(Math.random()*100));

Item item = document.replaceItemValue("YourFieldName", vector);
item.setSummary(false);

document.save(true,true);

You'll need to create a RichTextItem and use the methods on that object to populate it:

import lotus.domino.*;
import java.util.Vector;
public class JavaAgent extends AgentBase {
 public void NotesMain() {
   try {
     Session session = getSession();
     AgentContext agentContext = 
     session.getAgentContext();
     // (Your code goes here) 
     Database db = agentContext.getCurrentDatabase();
     Document doc = db.createDocument();
     Item subject = doc.replaceItemValue("Subject", 
     "Project description");
     RichTextItem body = doc.createRichTextItem("Body");
     body.appendText("Cartoon book for children 
      ages 9-12");
     // Print text of subject and body
     System.out.println(subject.getText());
     System.out.println(body.getText());

   // Save the document
     doc.save(true, true);
   } catch(Exception e) {
     e.printStackTrace();
   }
 }
}

UPDATE:

If you need to edit an existing document, instead of creating a new rich text item, you would get the existing one.

RichTextItem body = doc.GetFirstItem("Body");  // instead of createRichTextItem
