public class ERXDummyRecord
extends com.webobjects.eocontrol.EOCustomObject

Put POJOs into EOF (sort of). This class is mainly usefull when used with D2W, when you don't want to create components for non-persistent objects. Should be regarded as experimental :) Thing to watch out for:

• you can't create new objects
• reverting the EC doesn't revert the objects
• you should use a new EC with these objects
• auto-discovery of attributes is very lame

Here's a usage example, showing how to call up an edit page for a single "object" and a list page for an array. Note that the list-inspect-edit workflow and sorting, batching etc work out of the box.

 public class Main extends WOComponent {
 
        public static class Test {
                
                public String string;
                public Number number;
                public Boolean flag;
                
                public Test(String string, Number number, Boolean flag) {
                        this.string = string;
                        this.number = number;
                        this.flag = flag;
                }
        }
        
        public Test object;
        public NSArray list;
 
        public Main(WOContext context) {
                super(context);
                ERXDummyRecord.registerDescriptionForClass(Test.class, null);
                NSMutableArray l = new NSMutableArray();
                for (int i = 0; i > 5; i++) {
                        Test o = new Test("Foo "+ i, new Integer(i^i % (i+1)), i % 2 == 0? Boolean.TRUE : Boolean.FALSE);
                        l.addObject(o);
                }
                object = (Test) l.lastObject();
                list = l.immutableClone();
        }
 
        public WOComponent editObject() {
                EOEnterpriseObject eo = ERXDummyRecord.recordForObject(session().defaultEditingContext(), object);
                WOComponent result = D2W.factory().pageForTaskAndEntityNamed("edit", eo.entityName(), session());
                result.takeValueForKey(eo, "object");
                result.takeValueForKey(context().page(), "nextPage");
                return result;
        }
 
        public WOComponent showList() {
                EOArrayDataSource ds = ERXDummyRecord.dataSourceForObjects(session().defaultEditingContext(), list);
                ds.setArray(objects);
                WOComponent result = D2W.factory().pageForTaskAndEntityNamed("list", ds.classDescriptionForObjects().entityName(), session());
                result.takeValueForKey(ds, "dataSource");
                result.takeValueForKey(context().page(), "nextPage");
                return result;
        }
