Question

当我运行我的Kynetx应用程序时，我收到以下错误：

Can't use an undefined value as an ARRAY reference at /web/lib/perl/Kynetx/Persistence.pm line 284, <GEN0> line 465.

我的代码如下所示：

rule page_loaded is active {
  select when pageview "manticore.*" setting()
  pre {
    savedName = current ent:userName;
  }
  if (savedName neq "") then {
    notify("Hello #{savedName}!!","Welcome back!") with sticky = true;
  }
  notfired {
    raise explicit event name_not_saved_yet;
  }  
}

之前我有这个代码工作，不知道现在是什么杀了它。

更新从调试信息。

我们改变了存储路径的方式。我会尽快修复错误。

如果我向您展示一些秘密功能，您需要承诺不要告诉

为您的实体变量尝试语法（如果您有一个变量myUserName）：

 set ent:userName myUserName

然后，对于您的示例，您可以写：

pre {
  savedName = ent:userName || "";
}
if (savedName neq "") then ....

我们发布修补程序时会更新此答案
