    Stand alone dialogs are not working anymore when switching to 2012.2.724.40

    I rebuild with your KB  article code and keep getting:

    Bericht: Object reference not set to an instance of an object.

    [NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Web.UI.Editor.DialogControls.ImageManagerDialog.OnLoad(EventArgs e) +232
   System.Web.UI.Control.LoadRecursive() +74
   System.Web.UI.Control.LoadRecursive() +146
   System.Web.UI.Control.LoadRecursive() +146
   System.Web.UI.Control.LoadRecursive() +146
   System.Web.UI.Control.LoadRecursive() +146
   System.Web.UI.Control.LoadRecursive() +146
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2207

    Hi,

    I am aware of this issue with RadEditor external dialogs coming from the latest Q2 2012 SP1 release. The problem is logged in our Public Issues Tracking System with ID 12099 and the fix will be available in the next SP release.
    In the meantime I could provide you with a workaround - see the attached project here.

    Actually you need to apply the following line to each of the dialog definitions:
    Copy Code
    DialogDefinition imageManager = new DialogDefinition(typeof(ImageManagerDialog), imageManagerParameters);
    imageManager.Parameters["IsSkinTouch"] = false;
    ....
    DialogDefinition documentManager = new DialogDefinition(typeof(DocumentManagerDialog), documentManagerParameters);
    documentManager.Parameters["IsSkinTouch"] = false;

    I hope this helps.

    Kind regards,
    Rumen

    You wouldn't believe how hard it's been to find this exact page. Google really shows its flaws when your not looking for something well known and easy to express in English. 

    I can verify this workaround fixes the issue. 

    For others searching for this page, here's some tags to help google - DialogOpener, RadDialogOpener, ImageManager, "image manager 
    ", "Object reference not set to an instance of an object", telerik, stand-alone, "without RadEditor", "null reference", http://www.telerik.com/community/forums/aspnet-ajax/editor/image-editor-with-dialog-opener.aspx, http://www.telerik.com/support/kb/aspnet-ajax/editor/using-the-image-and-document-managers-outside-radeditor.aspx
