FileManager New Folder - Uncaught ReferenceError

[Doran]

Using FileManager in our app, and we are seeing the following exception when trying to create a "New Folder".   We do not see this error with any other operations, and are able to upload, rename, & delete files/folders without issue.   Is this a binding issue with our resulting json (see below)?  The funny thing is that this exception does not occur every time we click the "New Folder" button.  It shows up maybe 75% of the time. 

 

The exception is:

VM8695:3 Uncaught ReferenceError: extension is not defined
    at eval (eval at compile (kendo.all.js:234), <anonymous>:3:164)
    at init.refresh (kendo.all.js:70463)
    at init.proxy (jquery-3.1.1.js:502)
    at init.trigger (kendo.all.js:164)
    at init._process (kendo.all.js:7940)
    at init._change (kendo.all.js:7889)
    at init.proxy (jquery-3.1.1.js:502)
    at init.trigger (kendo.all.js:164)
    at init.splice (kendo.all.js:5008)
    at init.insert (kendo.all.js:7078)

 

 

Our FileManager datasource is a configured like this...

dataSource: {
    schema: kendo.data.schemas.filemanager,
    transport: {
        read: {
            url: "MyController/GetObjects/",
            method: "POST"
        },
        create: {
            url: "MyController/CreateObject/",
            method: "POST"
        },
        update: {
            url: "MyController/UpdateObject/",
            method: "POST"
        },
        destroy: {
            url: "MyController/DestroyObject/",
            method: "POST"
        },
    },
},

 

 

Our controllers method for CreateObject is:

[HttpPost]
public ActionResult CreateObject(string target)
{
    var result = myService.CreateFolder("NewFolder", target);
    return Json(result, JsonRequestBehavior.AllowGet);
}

 

 

And the json results are:

{
    "SId": "<guid>",
    "ObjectType": "Folder",
    "IsDirectory": true,
    "HasDirectories": false,
    "RootPath": "<some stuff>",
    "NameSpace": "<some stuff>",
    "Path": "myDir\\NewFolder",
    "Name": "NewFolder",
    "Extension": "",
    "Size": 0,
    "PathLocator": "<some stuff>",
    "ParentPathLocator": "<some stuff>",
    "Created": "\/Date(1593736985477)\/",
    "CreatedUtc": "\/Date(-62135571600000)\/",
    "Modified": "\/Date(1593736985477)\/",
    "ModifiedUtc": "\/Date(-62135571600000)\/",
    "Content": null
}

Hello Doran,

Looking at the posted dataSource configuration it appears you are using the Kendo UI for jQuery FileManager, not the UI for ASP.NET MVC one. If that is so, they use different schemas - the former uses camel case (e.g. "name": "NewFolder", "isDirectory": "true"), the latter uses pascal case (e.g. "Name": "NewFolder", "IsDirectory": "true"). So this is something you could try changing in your service.

Another thing I notice is the way the path is returned: "Path": "myDir\\NewFolder",

Try with: "path":"myDir/NewFolder"

Hello,

If you are using the MVC FileManager, change the names of the fields so that they start with capital letters (see my previous reply).
