Newbie: changing some attributes before saving

Hello,
This is a basic concept that I can't seem to get my brain to understand.
I have an entity called "webView" with an attribute called "headline".
When a user views a record and clicks a button (linked to an action "doUpdates") I want to change "headline" and other attributes and then save the record.
I've tried lines like...
webView.takeValueForKey("Hey, you clicked on the button", "headline");
or
webViewDisplayGroup.selectedObject().takeValueForKey("Hey, you clicked on the button", "headline");


and always seem to get a "can't resolve symbol" error on build.
What is the correct way to do this.

Below is a simplified version of the page. The page works fine except for the line in question.


//
// AdjustPagePreview.java: Class file for WO Component 'AdjustPagePreview'
// Project ContentDB
//
// Created by paul on 6/27/07
//


import com.webobjects.foundation.*;
import com.webobjects.appserver.*;
import com.webobjects.eocontrol.*;
import com.webobjects.eoaccess.*;

public class AdjustPagePreview extends WOComponent {
    public WebView webView;
    public WODisplayGroup webViewDisplayGroup;


public DeletePagePreview(WOContext context) { super(context); } public WebView webView() { return webView; }

    public void setWebView(WebView newWebView){
        webView = newWebView;
    }
  	

    public EditPage2 doUpdates()
    {
        EditPage2 nextPage = (EditPage2)pageWithName("EditPage2");

// webViewDisplayGroup.selectedObject() has an attribute of "headline"
// I want to change this data to something different
// something like the line below


webViewDisplayGroup.selectedObject().takeValueForKey("Hey, you clicked on the button", "headline"); // line in question

//this obviously doesn't work. What is the correct way to change some of the attributes
// before it is saved?

this.session().defaultEditingContext().saveChanges();

nextPage.webViewDisplayGroup.setSelectedObject ( webViewDisplayGroup.selectedObject() );


        return nextPage;
    }

}
