Grouping in scheduler doesn't work when setting data directly

[Christiaan]

I have a problem grouping the schedule. In the sample http://demos.telerik.com/kendo-ui/scheduler/resources-grouping-horizontal it shows how to achieve this, but if I replace the datasource with an array, it doesn't work anymore. As soon as I remove the grouping attribute the events show up in the scheduler.

You can find the repro in this dojo: http://dojo.telerik.com/UCUle/7. This has two scheduler controls, which are exact copies of each other, only the group is different. 

What am I doing wrong?

Hello Christiaan,

After checking the provided demo it appears that the reason for current behavior is the group configuration - the filed name is mistyped with lowercase "d". Please check the updated configuration below:

resources: ["roomID"]

On a side note I would like to remind you that without defining the Scheduler dataSource "schema.model" option the editing is not supported. You should either define this option or disable the Scheduler editing to avoid unexpected behavior.
