This call brings me 0 entries in the roles table why, am I doing something wrong or missing a piece of code

switch (CurrentUser.GetCapabilityAccess(capability.ID, Globals.GetRoles(this.Cache)))
{
caseENTRoleCapabilityEO.CapabilityAccessFlagEnum.None:
NoAccessToPage(capabilityName);
break;
caseENTRoleCapabilityEO.CapabilityAccessFlagEnum.ReadOnly:
MakeFormReadOnly(capabilityName, this.Controls);
break;
caseENTRoleCapabilityEO.CapabilityAccessFlagEnum.Edit:
//do not make this form read only.
break;
default:
thrownewException("Unknown access for this screen. " +
capability.CapabilityName);
}
