Hello! It seems like serialization to JSON does not work fine.
If you add a double quote to event name (i.e. badEvent"Name) and try to save contents of scheduler with scheduler.toJSON() you recieve JSON with unescaped quotes.
please find attached a fixed version of the serialize extension.
The fix will be also included in our next update.
Thanks for your assistance ! dhtmlxscheduler_serialize.js.zip (1.12 KB)
