处理GroovyPageView时出错：无法使用下一个使用grails注释事务前进

如果向控制器类添加注释事务，则视图中出现“错误处理GroovyPageView:无法使用next（）前进”错误

控制器

@Transactional(readOnly = true)
class SomeController {
    ...
    def sessionFactory

    def list(){
        def list = sessionFactory.currentSession.createSQLQuery( "some_query" ).scroll()

        [ list : list ]
    }
}

查看

...
<g:while test="${ list?.next() }"> <%-- exception here --%>
    <g:set var="instance" value="${ list.get() }"/>
...

以下是全部错误：

@Transactional

不应添加到Grails用于生成控制器的模板中。控制器应该很简单，可以与HTTP层一起工作，并调用服务来完成事务性工作和业务逻辑。从控制器中删除所有

@Transactional

注释，并将所有保存、更新和删除移动到一个或多个事务性服务，然后将服务注入控制器中。

跟踪中是否有其他东西表明真正的问题？虽然这里有

readOnly=true

，但您是否尝试过

@Transactional

only（默认为

readOnly=false

）？Tks@cfrick，我用这些信息更新我的问题
