Grails插件返回无效的流标头错误

Question

我有一个使用我创建的插件的Grails应用程序。两者都使用Spring-security-core插件。

我的插件有域类，控制器和视图。要显示的数据是从地图上绘制的线中选择的。返回的数据显示在浏览器窗口底部的列表中。我在其中一个应该显示所选记录的字段上创建了一个链接。

当我点击此链接时，我收到以下错误：

失败的代码是我尝试使用以下操作获取ID的数据：

@Secured(["hasRole('ROLE_MAP_USER')"])
def show(Long id) {
    println "ID: ${id}"
    def princObj = springSecurityService?.principal
    log.debug "User: ${princObj}"
    def bridgeInstance = RIMS.bridge.Bridge.get(id)
    if (!bridgeInstance) {
        flash.message = message(code: 'default.not.found.message', args: [message(code: 'bridge.label', default: 'Bridge'), id])
        redirect(action: "list")
        return
    }

    render(plugin: "nhvr", view:"show", model: [bridgeInstance: bridgeInstance])
}

返回的用户，退回到log.debug＆＃34;用户：$ {princObj}＆＃34;是正确的，并具有所需的角色。

我不知道该怎么办。任何人都可以建议尝试一下吗？

以下是Bridge类的代码：
