dhtmlxScheduler loses some events after going far in future

Hello, the problem is when I go far in future by clicking next button and than go back by pressing today or by prev button, some events, that were displayed on start screen were lost. Is it bug of dhtmlxScheduler or may be I doing something wrong?

Here is my config

scheduler.config.xml_date = "%Y-%m-%d";
scheduler.config.show_loading = true;
scheduler.config.readonly = true;
scheduler.config.start_on_monday = true;

scheduler.init('scheduler_here', new Date(), "month");


scheduler.load('/calendar_feed', 'json');


Unfortunately the problem cannot be reconstructed locally. Please, show your sample or link to problematic page.

Hello, unfortunately I can’t give you url to that page, but I can provide screncast I recorded youtu.be/O1QaWqMewdM

Unfortunately a screencast doesn’t help to understand the cause of the problem.

Try to add code to your app, but I’m not sure that it help. Possibly you have events with the same IDs in data and if you scroll to the second event of them, the first will not be displayed again. If it is realy so, this code should help.

scheduler.attachEvent("onBeforeViewChange", function (old_mode, old_date, mode, date) { if (old_mode != mode || +old_date != +date) scheduler.clearAll(); return true; });
