Question

我正在使用grails 2.0.0 M1和弹性搜索插件0.18.7.1-SNAPSHOT。

我可以安装它，并且可以使用默认配置看到它运行正常。我还可以看到我的域对象正在创建并成功添加到我的DBBootStrap.groovy文件的索引中。

...然而

当尝试仅从Web层创建（不保存）域对象时（在Bootstap脚本成功运行之后），我收到以下错误：

def testco = new Company(name:"test");

Line | Method

|   908 | run                   in     ''
^   619 | run . . . . . . . . . in java.lang.Thread

进一步调查显示堆栈跟踪与相关部分是......

相对较新的grails，我不知道如何创建域对象/ DataBinding可以在DBBootStrap上下文中工作，但不能在任何其他上下文中工作（服务/控制器。

非常感谢任何想法。

欢呼声。

... UPDATE

//works
def co =  new Company();
co.name = "hello"
co.save();

//doesn't work
new Company(name:"hello2").save();
