How to get rid of the "Starting Composition" scripting alert?

Hi,

I'm trying to use a script to render a composition from AE project from the command line, but each time I keep getting the modal dialog like this:

AE doesn't start rendering, until I hit OK, and I have no idea how to make this warning go away.

Any ideas?

found the issue on this. Somewhere along the line a library I was using has the lines:

function err(errString) {

        alert(errString) ;

    }

    app.onError = err;

Which looks benign because it appears only "errors" but I guess all the debug is being sent through as errors behind the scenes, including start/stop rendering info and it was converting them to alerts. Removed this, restarted AE( because it had cached it for some reason) and no longer occurring.

If you look at the CommandLineRenderer.jsx script (native script that comes with AE, to be found in Scripts/Startup, you'll see that unlike what is stated in the guide, app.onError has 2 arguments, the second one being the 'severity' of the error, so that you can filter your alert.

did anyone ever find out what this is? This just started happening on my script, no idea why and can't see if I clicked on anything. It's basically sending logging info to alert boxes every time it starts and stops rendering, these are not being generated by my script. Almost like AE debug kind of info, though Enable Logging is turned off.

Hi Bart,

Can't tell you exactly without script code, but if you will remove alert inside the code that contains "Starting composition"... , this might help you.

And if I do not have such an alert in my code?

There are app.beginSuppressDialogs() and app.endSuppressDialogs(showAlerts) that might help if the dialog was created by the application.
