Allow? Yes. AA doesn't control how you send hits, it's like a sponge that just "happily" accepts whatever you give it. But then, the resulting reports depends on how those hits are received. As you've discovered, if events are tracked before page views, then they can mess up your reports.
You didn't mention what kind of event you're using to track your error messages, so I'll assume that you meant a Direct Call. You also need a reliable way to know that a page load has occurred, and only then to allow the Direct Call to trigger.
One thing that you can try is the following: use 2 Rules with a _satellite.setVar().
Rule 1:
Event: Direct Call
Condition: Value Comparison: %page load occurred% is falsy
Action: custom code:
setTimeout(function() {
_satellite.track("..."); // run your direct call here
}, 1000);
Rule 2:
Event: Direct Call
Condition: Value Comparison: %page load occurred% equals "yes"
Action: track your error message.
and also Rule 0, your page load rule (I'm going to assume that you're using "Window Loaded" with this Rule):
Event: Window Loaded
Condition: ... whatever conditions you already have
Actions: whatever actions you already have, and also one more custom code action:
_satellite.setVar("page load occurred", "yes");Hope you can see the logic that I have here.
