Hi,
I'm working on GWT RPC and I have a problem with the method invocation
order; I have to invoke two methods m1() and m2() by this order (cause
m2 depends on the results of m1) but, I don't know why, the method
m2() is invoked before m1() even if I wrote: m1(); m2();
So, does RPC Asynchronous Callback implies that the methods could be
invoked out of order? If so, please how could I workaround that?
For more details, here is what I exactly do:
public RPCServiceAsync rpcService;
HashMap<Integer, ActiveCategory> active_cats;
public void onModuleLoad() {
...
load_categories();
load_objects(cat_id);
...
}
private void load_categories(){
rpcService.getCategoryList(new AsyncCallback<HashMap<Integer,
ActiveCategory>>(){
public void onFailure(Throwable caught) {
}
public void onSuccess(HashMap<Integer, ActiveCategory> result) {
active_cats = result;
}
});
}
private void load_objects(final int cat_id){
rpcService.getObjectList(cat_id, new
AsyncCallback<ArrayList<Integer>>(){
public void onFailure(Throwable caught) {
}
public void onSuccess(ArrayList<Integer> result) {
ActiveCategory cat = active_cats.get(cat_id);
cat.set_active_objects(result);
}
});
}
----------
public class ActiveCategory implements IsSerializable{
private int cat_id;
private boolean displayed = false;
private ArrayList<Integer> active_objects = new ArrayList<Integer>();
}
----------
In this example, always the load_objects() is invoked before
load_categories() !?? Please help!
