GWT Timer doesn't work

[Hanna Varakhobava]

Hello everyone!

I have a long operation and a progress bar that should be updated
every second.
Long operation is an RPC, that retrieve a collection with some
information. I call another RPC to know the progress of my operation.
I have Timer subclass, where in void run() I get a progress. I do the
following:

...

retrieveCollection(); // RPC, retunrs immediatly
runTimer();

...

public void runTimer(){
new Timer {...}.scheduleRepeating(1000);
}

The problem is that void run() starts only after the long operation is
finished, though sheduleRepeating() executes almost immediatly (i.e.
there is a long delay between execution of scheduleRepeating() and
run()).

Can you help me somehow? I want to get information about operation
progress while it's executing.

Regards,
Hanna Varakhobava

Has a solution been found to this issue? I have encountered the same
thing, with no luck.

You should execute the Timer right away, by directly calling its
run(). Then in the run() determine whether or not it needs to run
again. If so, use schedule(int) to make it run() again. The process
should be similar to how an IncrementalCommand would work...

Try this,

           Timer timer = new Timer() {
                 public void run() {
                     // Do Rpc. i.e., retrieveCollection

                     @Override
                     public void onFailure(Throwable throwable) {
                         // if needed
                         timer.schedule(100);
                     }

                     @Override
                     public void onSuccess(Result result) {
                         // do logic
                         timer.schedule(100);
                     }
                 }
             };
             timer.schedule(100);
