Unable to get skill number for all Avaya agents

[zygmuntix]

Hi, I am trying to retrieve information for all Avaya agents using Avaya SMS Web Service.
I am sending SubmitRequestType to Avaya with ModelFields created like that:

AgentType agentType = objectFactory.createAgentType();
modelFields.getAgent().add(agentType);

and 'list' operation. Many fields are generated correctly, for example 'extension' when agent is logged in to extension. However I cannot retrieve 'sn' field for all agents (I just get for example for one agent array with one element, empty string). When I am using 'display' operation for just 1 agent this is working properly.
How can I get 'list' operation work so that I get skill number for all agents?
Unfortunately there is no agentType.setSN() method... there is only 'getSN()' method.
