Hi, When is the onReset method called.. ??
In my case I have an ListBox I want to put in some values at startup...
so the data is there when the user loads the page.
The data is in the database, and I want to retrieve the data through a
SessionBean ( using JBoss )

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 ??

In my case I like to separate the "data layer" from the "presenter
layer" so its up to you how you retrieve your data, but for sure it will
be "ajax" underneath (for RPC or the same sort)
The onReset() get execute when the page loads...
So when you go to the page that will render that list, it will first
fetch data, in your case via RPC, then push the data to the view, then
the view will be displayed. I think all MVP framework works this way...
Perhaps you can look at this code: http://bit.ly/YIBxuQ
This implements a full MVP application, with code simple enough for you
to grasp the concept.
