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;
  }  
}

我之前有这段代码工作过，现在不知道是什么杀死了它。

我们改变了存储轨迹的方式。我会尽快修复错误。

如果我向您展示一些秘密功能，您需要保证不告诉

对于您的实体变量，请尝试使用语法（如果您有变量 myUserName）：

 set ent:userName myUserName

然后，对于您的示例，您可以编写：

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

当我们发布修复程序时，我会更新这个答案
