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?
