JSF2的Inputtext小部件将不允许用户在XHTML UI中输入数据

分类：编程问答

如何解决JSF2的Inputtext小部件将不允许用户在XHTML UI中输入数据

我正在将JSF1.1应用程序转换为JSF2。但是，我发现从初始视图导航到新视图时，inputText小部件将不允许从屏幕输入任何数据。使用锚标记或通过在浏览器中输入URL调用的初始视图不会发生此问题。我正在使用Wildfly 19.1 Primefaces 7.0和JSF 2.3。我该如何调试呢？

这是我的pom.xml文件。

        </f:view>
    </h:body>
</html>

这是从托管bean导航到上述UI的方法。

    public String returnToUserPage() {
        setXmlMsgs("");
        setClientCompanyName(getCompanyName());
        companyCheck();
        getClient().setLegalEntity(getClientCompany().getLegalEntityCompany());
        return "client";
    }

解决方法

确定，我需要做的是在导航时使用重定向选项。例如，上述方法应以

结尾

return "client?faces-redirect=true"
