HierarchyRequestError

[James Daresta]

I having a random problem recently with the last Q4 ASP.NET Ajax library. On occasion I get the following error. It seems to happen when one is editing the editor. I am posting here because the error message specifically mentions my script manager.

Message: HierarchyRequestError

Not sure it matters, but for my editors i have the following client script that has been in place for a while. I have been unsuccessful in tracking this issue down.

Telerik.Web.UI.Editor.CommandList.AjaxSpellCheck = function (commandName, editor) {
     var spell = $find('<%= radspellSpellChecker.ClientID %>');
     spell.spellCheck(new PrometheusTextSource(editor));
     return false;
 }

 var PrometheusTextSource = function (editor) {
     this._editor = editor;
     this.get_text = function () { return this._editor.get_html(); };
     this.set_text = function (value) { this._editor.set_html(value); };
 }

 function OnEditorLoad(editor, args) {
     editor.oldValue = editor.get_html(true);
     var element = document.all ? editor.get_document().body : editor.get_document();
     $telerik.addExternalHandler(element, "blur", function (e) { var ed = editor; var newValue = ed.get_html(true); if (ed.oldValue != newValue) Master_SetFormChanged(); });
 }

 function OnClientModeChange(sender, args) {
     if (sender.get_mode() == 4) // Checking the mode, where mode 4 is Preview
     {
         sender.get_toolContainer().style.display = "none"; // Hide ToolBar
     }
     else {
         sender.get_toolContainer().style.display = "block"; // Show ToolBar
     }
 }

Hello James,

The only known reason for the HierarchyRequestError error is when the RenderMode property of RadEditor is set to Lightweight and ToolbarMode is RibbonBar. Can you check whether this is the case at your end?

If this is causing the issue upgrade to the latest version R1 2017 SP1 (2017.1.228) and test again.

If the problem still persists, please provide reliable reproduction steps on how to reproduce it on our end.

Best regards,
Rumen
