Hi all,

 

I used the CuteWebUI_AjaxUploader_OnSelect event in order to validate the filename:

 

    function CuteWebUI_AjaxUploader_OnSelect(files)
    {
        var name = files[0].FileName;
        var size = files[0].FileSize // (or -1)

        DoValidationCallBack(name);

        debugger;
        
        if (callbackResult.indexOf("ok") != 0) {
            
            return false;
        }
    }

Validation is performed on server side using callback. So if it fails I return false. At this moment the "'arr' is undefined" message is popped up by the browser. Debugger show, that it was thrown from CuteWebUI_Uploader_Resource.axd?type=script&_ver=633886310254119016.

 

What should I do to avoid this message?
