Hi Lucio

I can't find the project where I had to do it, but I've looked at the archetype.js file again and I think I remember all you have to do is edit the getNativeLabel function to add in the Umbraco.ContentPickerAlias case in the switch statement:

    function getNativeLabel(datatype, value, scope) {

    switch (datatype.selectedEditor) {
        case "Imulus.UrlPicker":
            return imulusUrlPicker(value, scope, {});
        case "Umbraco.TinyMCEv3":
            return coreTinyMce(value, scope, {});
        case "Umbraco.MultiNodeTreePicker":
            return coreMntp(value, scope, datatype);
        case "Umbraco.ContentPickerAlias":
            return coreMntp(value, scope, datatype);                
        case "Umbraco.MediaPicker":
            return coreMediaPicker(value, scope, datatype);
        case "Umbraco.DropDown":
            return coreDropdown(value, scope, datatype);
        case "RJP.MultiUrlPicker":
            return rjpMultiUrlPicker(value, scope, {});
        default:
            return "";
    }
}

You can find the file in App_Plugins > Archetype > js > archetype.js
