Groovy Script to retrive roles

Hi all,

i want to retrive roles related to my account, i used this code:

def vo = newView('Resource');

def vc = vo.createViewCriteria()

def vcr = vc.createRow()

def vci1 = vcr.ensureCriteriaItem('PartyId')

vci1.setOperator('=')

vci1.setValue(adf.util.getUserPartyId())

vc.insertRow(vcr)

vo.appendViewCriteria(vc)

vo.executeQuery()

if(vo.hasNext()) 

{

def r = vo.next()

def x = r?.Roles.toString()

println(x); 

 }

The value of x is 'Channel Account Manager,Channel Sales Manager' but i have also other roles, why i can retrive only these roles??

Can you kindly help me?Thanks
