I believe requestfactory and new feature such as cell widget and cell
table should be development paradigm to work in tandem, but I found
that they might not work as expected, I don't know it's a bug or just
I don't know how to use it right.
The symptom is when using entity proxy as the <T> in celltable and
selectionModel creation process, onSelectionChange event won't be
triggered; if I get rid of keyProvider in selectionModel and celltable
creation ,the onSelectionChange will be triggered, but I still can not
get the selected object by using ' selected =
selectionModel.getSelectedObject();'
Below is entity proxy,celltable creation code snippet:
*ContactProxy.java
@ProxyFor(Contact.class)
public interface ContactProxy extends EntityProxy {
Long getId();
String getName();
String getAddress();
void setName(String name);
void setAddress(String address);
void setId(Long id);
}
______________________________________
*cellTable creation
private void createTable() {
table = new CellTable<ContactProxy>(keyProvider);
// Create name column
TextColumn<ContactProxy> nameColumn = new
TextColumn<ContactProxy>() {
public String getValue(ContactProxy object) {
return object.getName();
}
};
// Create address column
TextColumn<ContactProxy> addressColumn = new
TextColumn<ContactProxy>() {
public String getValue(ContactProxy object) {
return object.getAddress();
}
};
// Add a selection model to handle user selection.
final SingleSelectionModel<ContactProxy> selectionModel =
new SingleSelectionModel<ContactProxy>(keyProvider);
table.setSelectionModel(selectionModel);
selectionModel.addSelectionChangeHandler(new
SelectionChangeEvent.Handler() {
public void onSelectionChange(SelectionChangeEvent event) {
ContactProxy selected = selectionModel.getSelectedObject();
Window.alert("ok" + selected.getId());
if (selected != null) {
clientFactory.setSelectedContactId(selected.getId().toString());
}
}
});
table.addColumn(nameColumn, "Name");
table.addColumn(addressColumn, "Address");
}
my guess is selectionModel does not welcome interface, is that right?
thank you .
