layoutTitle标记问题

标签： grails gsp

我正致力于一个grails项目。所以在它的主要布局页面中有一个字符串

 <title>CHP: <g:layoutTitle /></title>

并且每个视图页面都有一个标题标记。但我发现在HelperMethodsTagLib（在同一命名空间内）中的layoutTitle标签被覆盖：

def layoutTitle = { attrs, body ->
        try {
            out << this.pageScope.settedPageTitle
        } catch (Exception e) {
            out << "Default"
        }
    }

此实现不起作用，因此每个页面都有标题CHP：Default。 删除此实现会导致应用程序失败：
