Hello!
I have a problem. I am calling to server side on GWT. The results of
call is an ArrayList (result). Inside onSuccess method another
ArrayList is wrapped with the result. However, if I want to use
ArrayList lista outside of onSuccess method it contains 0 elements,
but inside is like result ArrayList. How can I solve it? I have tried
to use lista as class attribute, static attribute,... but it doesn't
run.
Thanks!
public void addContainers() throws Exception {
final ArrayList<String> lista = new ArrayList<String>();
gwtService.obtainAttributesDevice(1, new
AsyncCallback<ArrayList<String>>(){
@Override
public void onFailure(Throwable caught) {
System.out.println("ERROR");
Window.alert(caught.getMessage());
}
@Override
public void onSuccess(ArrayList<String> result) {
RootPanel.get("mainContainer").add(new
Label("Array result:
"+result.toString()));
RootPanel.get().add(new
Label(String.valueOf("Array result:
"+result.size())));
lista.addAll(0, result);
RootPanel.get("mainContainer").add(new
Label("Array lista 1:
"+lista.toString()));
RootPanel.get().add(new
Label(String.valueOf("Array lista 1:
"+lista.size())));
}
});
RootPanel.get("mainContainer").add(new Label("Array lista 2:
"+lista.toString()));
RootPanel.get().add(new Label(String.valueOf("Array lista 2:
"+lista.size())));
for(int i = 0; i < lista.size(); i++){
RootPanel.get().add(new Label("BOTON "+i));
}
}
