public class UserForm {
	private UserService userService;

	private User user;

		log.debug("getUserTeamIds go here..");
		List<String> li=new java.util.ArrayList<String>();
		if(user!=null){
			Set<Team> teams=user.getTeams();
			for (Iterator<Team> itr=teams.iterator();itr.hasNext();){
				Team r=itr.next();
				li.add(r.getTeamId().toString());
			}
		}

	}


	/**
	 * for select many
	 * @return
	 */
	public Map<String,String> getUserTeamMap(){

		java.util.Map<String,String> m=new java.util.LinkedHashMap<String,
String>();
		if(user!=null){
