ImageManager javascript error on empty directories

[Colin]

I'm working with the ImageManager in the RadEditor and run across very simple problem -- uploading an image when the directory currently being viewed is empty causes a javascript error that breaks the ImageManager until the page is reloaded.  However, if the directory isn't empty, everything works fine.

Surely I am doing something wrong, but I've stripped almost everything out of my code and the issue persists.

Here is my markup:

<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
    CodeBehind="Default.aspx.vb" Inherits="ImageMgrTest._Default" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <asp:ScriptManager ID="ScriptManagerProxy1" runat="server"/>
   <telerik:RadEditor ID="txtRegText" Width="100%" runat="server"
        DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.axd"
        StripFormattingOnPaste="MSWord">
        </telerik:RadEditor>
</asp:Content>

And the code behind:

Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim uploadPath As String = "~/uploads"

        Me.txtRegText.ImageManager.UploadPaths = {uploadPath}
        Me.txtRegText.ImageManager.ViewPaths = {uploadPath}
        Me.txtRegText.ImageManager.DeletePaths = {uploadPath}

        Me.txtRegText.ImageManager.MaxUploadFileSize = 1024 * 1000
        Me.txtRegText.ImageManager.SearchPatterns = New String() {"*.jpg", "*.png", "*.gif", "*.jpeg", "*.bmp", "*.tiff"}

    End Sub

End Class

If the "/uploads" directory is empty when you go to add an image via the image manager, you get this javascript error after the image is uploaded:

93Uncaught Sys.ArgumentOutOfRangeException: Sys.ArgumentOutOfRangeException: MinimumValue should be smaller than maximumValue Parameter name: _minimumValue Actual value was 0. 

Anyone seen this before?

Hi,

Please, download the latest internal build of RadControls for ASP.NET AJAX from your account and test it? The error should be fixed in it. The issue will not happen in the upcoming Q1 2012 Service Pack 1 release too.

I am experiencing the same issue.  Are you able to tell me when the SP will be released so that I don't have to use an internal build for production?
