Hi there,

I'm developing an application and experience such a problem:
"Permission denied to all viewer resources" error when trying to get viewer data. The error occurs when the app is run by another developer (from app developers list). When I run the app myself or test it with MySpace tools it works fine.

Can anyone help with it? Below there's the source code and trace.

<div id='loading'><img src='http://www.viphaklay.com/jquery/spinner.gif'/></div><div id='message' style='margin: 4px'></div>

Trace with error (run by an app developer):

Trace Info:
Init
Sending request to MySpace
The request has been sent successfully
We got to request callback function
there was an error requesting data from MySpace:
unauthorized Permission denied to all viewer resources.

Trace without error (run by me):

I found out that this happens if the developer does not have the app installed. After they install it everything is OK. But I'm not sure that this behaviour is correct. Does a user have to install an app? They might be just visiting a friend's profile where this app is installed.

So I think the issue is not closed.

 Thanks for the feedback, I'll check into it.

Hey, are you talking about regular users or developers?

In dev mode you must be the developer or have the app installed to view it.

Yes, thanx. That was the case.
