Okay... for starters, what version of GWT are you using? With 1.4, you're
not going to be able to use parameterized types on the client side. With
1.5, you can use parameterized types.
For 1.4:
AsyncCallback callback = new AsyncCallback() {
public void onSuccess(Object result) {
List list = (List)result;
Iterator i = list.iterator();
while (i.hasNext()) {
ProgrammerTO item = (ProgrammerTO)i.next();
// Do stuff
}
};
For 1.5:
AsyncCallback<List<ProgrammerTO>> callback = new
AsyncCallback<List<ProgrammerTO>>() {
public void onSuccess(List<ProgrammerTO> result() {
for (ProgrammerTO item : result) {
// Do stuff
}
}
};
With 1.4, you cast everything to the desired type. With 1.5, you
parameterize.
