Keycloak注册模板加载错误

我在尝试在keycloak领域注册新用户时发生错误。我在Mac Yosemite上以独立模式运行keycloak。我是keycloak的新手，但已成功创建了一个新领域并将其配置为与本地托管的Apache Web服务器提供的html/js示例页面一起工作。总之，印象非常深刻;但只想弄清楚我在做这个register.ftl错误。Keycloak注册模板加载错误

感谢任何指针。

这里的错误：

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>.

你能后的模板？好像第46行的密码是必需的，但没有设置。 –

在我的经验，这主要是由于在形式设置没有默认/后备值为空属性。您可以确保该属性不能在你的服务被设置为空或提供一个默认值：

myOptionalVar!myDefault

或：

<#if myOptionalVar??> 
    when-present 
<#else> 
    when-missing 
</#if>
