info.magnolia.module.templating.RenderException:找不到null类型的呈现器

Question

我在eclipse中创建了一个empty webapp project，并添加了magnolia STK依赖项来使用它。我使用empty webapp project将tomcat部署到服务器。现在，我想像描述的first page template那样创建我的这里。在创建页面之后，当我打开创建的页面(在hello.html ->打开页面上的网站右键单击)时，我会得到以下异常：

Mybe是我将freemarker类型设置为String的问题吗？？但只有4种类型见附件

​

Answer 1

我找到了解决办法。在前面提到的教程中，type称为renderType。用renderType代替type解决了

Answer 2

如果你用它来做印版，renderType必须是"stk“。
