Answer 1

在您的XHTML

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

映射到

HtmlInputText type; 

這是不對的。該值應該映射到String類型的variable。

變化：

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

使上述變化和嘗試，它應該工作。

僅供參考 - 僅對binding使用HtmlInputText。但你不需要綁定在這裏。
