我在单击命令按钮时添加行动态。其中我有两个文本字段和一个下拉列表，最后一列已保存。我能够保存已经在数据库中的旧数据，但无法保存新添加的行。当我单击保存 commandLink 时，实际上控制没有到达 bean。

UOMDTO 是
private Country country;
private Language language;
private String uomDisplayName;
private String uomDescription;
private List<UOMDetailDTO> uomList;
private Integer measureTypeId;
和 UOMDetailDTO 是
private String languageName;
private String languageCode;
private String languageValue;
