I have been having a problem with trying to edit a second time after pressing cancel the first time. I found a kendo example which demonstrates my problem: https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/binding/using-local-observable-data-object

I clicked cancel when editing an event. Then double clicked the event again to edit and it did not work. In the example it will only redisplay the edit screen if you press the "update" button first. But after that you can open the edit screen and press cancel as many times as you like.

Can you help fix this?

I am using a local datasource so I don't use transport do I? Under the transport section it says "Local data sources are bound to a JavaScript array via the data option.".

I believe I have done this in my Scheduler code. Could you provide me with a dojo example of Scheduler using a local datasource that is edited multiple times? The original link (https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/binding/using-local-observable-data-object) I mentioned is Scheduler using a local datasource. But does not work unless the 1st time round you click the "update" button even though I pressed cancel.

Thank you.

Here is a link to documentation on handling CRUD operations in your scheduler. You will set up a transport, and pass the created/updated/destroyed event to e.success in each CRUD operation (except read, where you pass the entire array of scheduler events to e.success()). 

I believe your current binding to local array of data is fine for viewing events... but when you want to edit/create/delete/etc... you should define a transport in your dataSource.
