Mapmanager calls - Server only?

[.:HyPeX:.]

As the title says, are mapmanager calls ( exports ) server only?

I'm reciving "call failed" from client so far.

Error:

call: failed to call 'mapmanager:getMapsCompatibleWithGamemode' [string "?"] 

  
local maplist = exports.mapmanager:getMapsCompatibleWithGamemode( getResourceFromName('race') )  

However command "maps race" returns:

  
'race' has 7 maps: 
-FUN-airplaNe---Reality ([FUN] airplaNe - Reality)  
KiwiVol7 ([DM] Kiwi Vol.7 - Perception)  
[DM]AbodyRulez-Vol6-Seven-Deaths ([DM]AbodyRulez Vol.6 - Seven Deaths)  
[DM]OldSchoolSkillZ ([DM]>>|-Old_School_SkillZ-|<<)  
[DM]ZeroCool_-v4-_Dirty_Imaginations ([DM] ZeroCool vol.4 - Dirty Imaginations)  
editor_test ([DM] ZeroCool vol.4 - Dirty Imaginations)  
hypex-testtop (Hypex-Testtopmap)

Yeah, I think that you could only get the table server side. You should send the table to the client.
