How to get value of PartyList field using Javascript and oData in CRM 2011

due to CRM 2011 online problems with IE10, we have decided to convert all
front-end JavaScript from Soap to oData. Everything was going fine, I
installed the oData designer, centralized the queries in functions, but i
ran into a problem when i tried to retrieve the partylist field Resources
for ServiceActivity.
The oData query I got using the oData Query designer is the following (the
guid is a sample)
ServiceAppointmentSet?$select=Resources&$filter=ActivityId eq
guid'83CA6B11-6C0A-E311-8BB5-B499BAFE71A5'
but in the response i get an error that the Resources field was not found.
I tried without the select, and debugged the returned oData object, but
noticed that it doesn't show both Resources and Customers partylist fields
that are in ServiceActivity.
ServiceAppointmentSet?$filter=ActivityId eq
guid'83CA6B11-6C0A-E311-8BB5-B499BAFE71A5'
Does anyone have any ideas?
