I’m making a number of save calls repeatedly after one another, and when I continue a few times, I eventually see the following Exception:
AndroidRuntime: FATAL EXCEPTION: main

Please provide a code snippet which we can run to see the error.

Here are some code snippets which hopefully will help:
I invoke my call from my adapter. I have a click listener on a button inside my getView method:
@Override
public View getView(int position, View convertView, final ViewGroup parent) {
final View view = LayoutInflater.from(mContext).inflate(R.layout.content_recipe_element, parent, false);
final ImageView button = (ImageView) view.findViewById(R.id.btn_favourite);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PartyController.getInstance(mContext).saveParty(party.clone());
}
});
return view;
}
Below is PartyContoller which extends Controller, which is:
public class Controller {
protected JobManager mJobManager;
public Controller(Context context) {
Backendless.initApp(context, PartyPlannerConfig.BACKENDLESS_APP_ID,
PartyPlannerConfig.BACKENDLESS_SECRET_KEY,
context.getResources().getString(R.string.backendless_app_version));
mJobManager = PartyPlannerApplication.getInstance().getJobManager();
}
}
And here is PartyController:
public class PartyController extends Controller {
final private static String WHOAMI = "UserController";
private static PartyController instance;
public PartyController(Context context) {
super(context);
}
public synchronized static PartyController getInstance(Context context) {
if(instance == null) {
instance = new PartyController(context);
}
return instance;
}
public void getPartyList() throws UserException {
mJobManager.addJobInBackground(new GetPartyListJob());
}
public void saveParty(Party party) {
final Calendar c = Calendar.getInstance();
party.setUpdated(c.getTimeInMillis());
PartyPlannerConfig.setCurrentParty(party);
mJobManager.addJobInBackground(new SavePartyJob(party));
}
}
And here is my SavePartyJob:
public class SavePartyJob extends KellogsJob {
private static String WHOAMI = "SavePartyJob";
private Party mParty;
public SavePartyJob(Party party) {
super();
mParty = party;
}
@Override
public void onRun() throws Throwable {
Backendless.Persistence.of(Party.class).save(mParty,
new AsyncCallback<Party>() {
@Override
public void handleResponse(Party response) {
PartyPlannerLog.v(WHOAMI, "Party Saved");
EventBus.getDefault().post(new SavePartyResultEvent(response));
}
@Override
public void handleFault(BackendlessFault fault) {
PartyPlannerLog.v(WHOAMI, "Party not Saved");
EventBus.getDefault().post(new SavePartyResultEvent());
}
});
}
}
Below is SavePartyResultEvent:
public class SavePartyResultEvent {
Boolean mSuccess;
Party mParty;
public SavePartyResultEvent() {
mSuccess = false;
}
public SavePartyResultEvent(Party response) {
mParty = response;
mSuccess = true;
}
public Boolean isSuccess() {
return mSuccess;
}
public Party getParty() {
return mParty;
}
}

Hello @Yusuf,
Could you please compile new project reproducing this specific problem and also provide us data export. Please send the project and data export to support@backendless.com.
Artur
Hi Yusuf,
Thanks for sharing the code. To reproduce the problem, we would need a full closure of the Party class. That means would need to have all the classes to get Party to compile. Could you please create a zip file and upload to either google drive or dropbox and email the link to support@backendless.com?
Regards,
Mark
Hey there, I seem to be having the same issue here. I’m trying to update something over and over again. Basically I’m sending a train of updates to that one object, but the update fails at some point with that aforementioned exception.
What should one do here?
Salman,
Does your code happen to modify the object on the client while it is “in transit” to the server?
Mark
The request are made through async calls, so I guess some request are being sent out while the previous request is still taking place.
How do I handle this?
You could try making a copy of the object you sent out and on work on a copy instead.
