Unable to get Bean Model Data Grid working . Can anyone help me out on why my data grid is not working . I checked the callback object . Its comming up right from the server . Here is my code .
Just the data grid with collumn header comes up .
MY DTO : EmpCounty implements BeanModelTag, Serializable

VerticalPanel vp = new VerticalPanel();

// proxy and reader
final RpcProxy proxyB = new RpcProxy() {
@Override
public void load(Object loadConfig, AsyncCallback callback) {
String key = “israel”;
myService.loadObject(key, callback);
loader.load();

}
};

BeanModelReader reader = new BeanModelReader();

// loader and store
ListLoader loader = new BaseListLoader(proxyB, reader);
ListStore store ;
store = new ListStore(loader);
loader.load()

// column model
List columns = new ArrayList();
columns.add(new ColumnConfig(”name”, “name”, 200));
columns.add(new ColumnConfig(”country”, “country”, 100));
ColumnModel cm = new ColumnModel(columns);

Grid grid = new Grid(store, cm);
grid.setAutoExpandColumn(”country”);
grid.setHeight(300);

vp.add(grid);

RootPanel.get().add(vp);

Any idea on how to wire Enteprise Java Beans over the wire? First problem is that the EJB wont compile in gwt becouse they relate to annotatioons in javax.persistence.*; Medyum ; I then made fake annotation files, that made the gwt js compile and run. But then the gwt-servlet fails to serialize the beans for transmission

Any progress about this issue? Deferred binding for BeanModel works in hosted-mode browser, but it does not compile for deployment.
