I have a number of DataSource items in the event editor template. They are small JSON objects and it would be dumb to read them from the server each time. They do not change and are part of the page load. You can see here I am just serializing them into the page itself:
This works 9 out of 10 times. But sometimes the dataset is empty. Which is crazy because I am always filling it. I managed to find a work around on the event edit event that gets called but this seems strange to do. Not sure if there is a true bug here or not. Feels like it because this code should not have been needed:
Oddly I can reproduce this every time now. The kendo.data.DataSource never seems to be initialized. In fact, I can reproduce this without a web site just using the browser F12 window console. In this case I limited my objects to 2 objects for shortened code. It was an intermittant thing. Had this been always the case I would not have opened a bug request for it.
Now it happens 100% of the time with just the code below. You can see the read() method is required. Is this my misunderstanding?
Here's the console.
If it helps, here is what was pasted:
var foo = new kendo.data.DataSource({
data: [{"Id":10,"Abbreviation":"AR","ColorHtml":"#DCA5C9","TextColorHtml":"Black","Description":"Assignment Review"},{"Id":4,"Abbreviation":"EA","ColorHtml":"#FF0000","TextColorHtml":"White","Description":"Estimate Appointment"}]
});
// returns 0
foo.data().length;
foo.read();
// returns 2
foo.data().length;
