ESTK ignores try/catch during debugging

I'd love to be able to mark an answer here, but the Adobe forums have been

blocked off to me for days; I just get the dreaded redirect bug which is I

guess a standard feature now. Thanks for looking into this, folks, and if I

can ever log back in I'll happily mark this closed given the tip about

levels.

For example, I use this to get annotations on an image document on photoshop.

Running from ESTK it breaks on try/catch

How could I use isValid() to prevent that?

function getAnnotationCount () { 

    var index = 0; 

    while (hideAnnotation (index)) { 

        index++; 

    } 

    return index; 

    // Dummy action, only used to test the existence of an annotation by index... 

    function hideAnnotation (index) {

        var exists = true; 

        var desc = new ActionDescriptor (); 

        var ref = new ActionReference (); 

        ref.putIndex (stringIDToTypeID ('annotation'), index); 

        desc.putReference (stringIDToTypeID ('target'), ref); 

        try { 

            executeAction (stringIDToTypeID ('hide'), desc, DialogModes.NO); 

        } catch (e) { exists = false; }     

        return (exists); 

    }

}
