Hi, I am trying to load some data for a ListBox on startup..
I have this in the onModuleLoad method
private final PrintProviderMockServiceAsync ppmockService =
GWT.create(PrintProviderMockService.class);
....
....
ppmockService.getPrintProviders(new
AsyncCallback<ArrayList<PrintProviderMock>>() {
@Override
public void onSuccess(ArrayList<PrintProviderMock> arg0) {
for (PrintProviderMock printProviderMock : arg0) {
comboBox.addItem(printProviderMock.getName());
}
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
Anyone got some good ideas how to load data into various widgets on
startup ??

I'm not entirely sure of what did you mean by load data into widgets at
startup, but in my case I use MVP framework do handle this kind of problem.
Where the presenter fetches data from service and assign values to the
view accordingly, is that what you want?
Example:
// Presenter code
@Override
protected void onReset() {
super.onReset();
// Add your RPC code here
ppmockService.getPrintProviders(new
AsyncCallback<ArrayList<PrintProviderMock>>() {
@Override
public void onSuccess(ArrayList<PrintProviderMock> arg0) {
for (PrintProviderMock printProviderMock : arg0) {
getView().addItemToComboList(printProviderMock.getName()); // notice this
}
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
}
// Presenter code
You can use GWTP (GWT Platform for MVP)
