Thank you for your reply....
but with this solution it seems that I am forced to interlink several
anonymous classes... For example :
saveButton.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event){
someAsyncService.*checkData*(valueToCheck, new
AsyncCallback<ObjectSavedToDatabase>(){
public void onSuccess(ObjectToCheck checkedObject){
if(checkedObject){
someAsyncService.*save*(createObjectToSave(),
new
AsyncCallback<ObjectSavedToDatabase>(){
public void
onSuccess(ObjectSavedToDatabase savedObject){
///Now do your
screen change logic
}
public void onFailure(Throwable
throwable){
//handle exception
}
});
}
}
public void onFailure(Throwable throwable){
//handle exception
}
});
Interlinking anonymous classes is the only avalaible solution?
Thanks for your answers
