Cancel Suffix Number Addition When Reopen Raw filess (CR2)

I'll post an updated version... If you are not opening the raw files as smart objects, I'll need to modify the previously linked script...

Edit: @Shlomit Heymann – here is the updated version for use with raw files from ACR which are not smart objects. Please let me know if there are any issues and or if it works OK for you:

            var xmp = new XMPMeta(activeDocument.xmpMetadata.rawData);
            var crsMeta = xmp.getProperty(XMPConst.NS_CAMERA_RAW, "Version");
            if (activeDocument.name.match(/-\d+$/) && activeDocument.activeLayer.isBackgroundLayer && activeDocument.layers.length === 1 && crsMeta !== undefined) {
                var origDoc = activeDocument;
                var docName = origDoc.name.replace(/-\d+$/, '');
                origDoc.duplicate(docName, false);
                origDoc.close(SaveOptions.DONOTSAVECHANGES);
                // END OF SCRIPT NOTIFICATION
                app.beep();
            }
        }
    }

    // ALERT IF NO DOCS OPEN
} else {
    alert('You must have a document open!');
}

The script is intended to be used via the Script Events Manager for the Open Document event:
