Can't use EventDate or EndDate when filtering calendar items using REST api

Hi everyone,

I'm having trouble, and I'm not the only one with filtering calendar events using the EventDate or EndDate fields.

I'm trying the following query using REST api:

/_api/web/lists/getbytitle('calendar')/items?$filter=(EventDate  ge  datetime'2013-01-26T22:00:00Z')&$select=Title,EventDate,ID

and I'm getting the following error:

The field 'EventDate' of type 'DateTime' cannot be used in the query filter expression

Anyone know how to bypass this? Is this a bug?

I already have a JavaScript ready to accept JSON, so accepting data from ListData.svc is a bad option.

Thanks,

Amir
