Detailed Description

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;
 	}
 }
