Anyone been able to add record to RESTDataSource ?

[kenandr]

Hi,

Have any of you been able to add a Record to a RestDataSource with dataFormat JSON ?

The following code give an error:

                final Record newRecord = new Record();
                newRecord.setAttribute(XDataSource.FIELD_A, "a");
                newRecord.setAttribute(XDataSource.FIELD_A, "b");
                newRecord.setAttribute(XDataSource.FIELD_CREATED_AT, new Date());
                

                xDataSource.addData(newRecord, new DSCallback() {
                    @Override
                    public void execute(DSResponse dsResponse, Object o, DSRequest dsRequest) {
                        if (dsResponse != null && dsResponse.getData() != null && dsResponse.getData().length == 1) {
                            eventBus.fireEvent(new XWindowEvent(dsResponse.getData()[0], XWindowEvent.Kind.OPEN));
                        } else {
                            SC.say(messageConstants.errorCommunicatingWithServer());
                        }
                    }
                });

The stacktrace in the Developer Consoel is:

Could it be a GIN/EventBus problem ?

I've isolated the RestDataSource and the addition of the Record to the datasource using samples/helloworld-2.0 and it works (using smartgwt trunk).

Could it be that the usage of GIN/eventbus is the root to this problem ?

Will try to compile smartgwt-trunk with smartclient-trunk now to see if that solves the problem first.

It works with smartclient-trunk
