Hi i added the parameter names...
the last parameter is the distinct. If that is set to true
the cloud.getList skips the number fields .so it's not possible to do
getNodeValue("rolerel");
it's possible that that is the problem/bug you need to add rolerel.number to the list
of required fields
or try changing the true to false
