我无法在我的 bean 中获取输入文本值

我在工作流程中将覆盖 bean 设置为会话 bean，但是当我尝试从输入文本中获取值时，它返回 null

Answer 1

在你的 XHTML 中

<p:inputText id="type_inp1" value="#{coverageBean.type}" /> 

映射到

HtmlInputText type;

这是错误的。该值应映射到 variable 类型的 String。

变化：

private String type;
    public String getType() {
        return type;
    }
    public void setType(Stringtype) {
        this.type = type;
    }

进行上述更改并尝试它应该可以工作。

仅供参考 - 仅将 HtmlInputText 用于 binding。但是你不需要在这里绑定。
