我试图绑定到第一个自定义组件中的第一个文本输入，以及在第二个自定义组件中查找关联文本输入并将其值检查为空和null的方法。但当我在pery input中插入一行时，第二个输入将被插入调试器input.getValue（）。ToString（）等于用户输入的值，而不是实际值。为什么会发生这种情况？我如何通过编程在侦听器中获得真正的价值

PS，因此我在DOM树中查找组件：

 public static UIComponent findComponent(final String id) {
    FacesContext context = FacesContext.getCurrentInstance();
    UIViewRoot root = context.getViewRoot();
    final UIComponent[] found = new UIComponent[1];

    root.visitTree(new FullVisitContext(context), new VisitCallback() {
        @Override
        public VisitResult visit(VisitContext context, UIComponent component) {
            if (component.getId().equals(id)) {
                found[0] = component;
                return VisitResult.COMPLETE;
            }
            return VisitResult.ACCEPT;
        }
    });

    return found[0];
}

@ManagedBean
@SessionScoped
public class MergeBean implements Serializable {

    private Person selectedPerson;

    public MergeBean() {
    }

    public Message getMerge() {
        if (this.merge == null) {
            this.merge = new Message();
            this.merge.setInputData(new Message());
        }
        return this.merge;
    }

    public void setMerge(Message merge) {
        this.merge = merge;
    }

    public void changeField(AjaxBehaviorEvent event) {
        String id = event.getComponent().getId();
        String valStr = ((HtmlInputText) event.getComponent()).getValue().toString();
        if (valStr != null && !valStr.isEmpty()) {
            String idChange = id.substring(0, id.length() - 5);
            UIInput input = (UIInput) UtilsUIXhtml.findComponent(idChange + "Second");
            //TODO
            Object objTemp = input.getSubmittedValue();
            //String tempStr = objTemp.toString();
            String cngStr = input.getValue().toString();
            if (cngStr == null || cngStr.isEmpty()) {
                input.setValue(valStr);
            }
        }
    }
}

 public static UIComponent findComponent(final String id) {
    FacesContext context = FacesContext.getCurrentInstance();
    UIViewRoot root = context.getViewRoot();
    final UIComponent[] found = new UIComponent[1];

    root.visitTree(new FullVisitContext(context), new VisitCallback() {
        @Override
        public VisitResult visit(VisitContext context, UIComponent component) {
            if (component.getId().equals(id)) {
                found[0] = component;
                return VisitResult.COMPLETE;
            }
            return VisitResult.ACCEPT;
        }
    });

    return found[0];
}
