R.get_canAcceptTrackChange is not a function error when using ToolProviderID

I've been trying to upgrade an existing solution to use the latest release version (2019) of the Telerik UI for ASP.NET AJAX and have encountered a major problem with the 'Tool Provider', a technique which is significantly used in my solution. This same error displays in your own Telerik Demo. Details are:

Description of the issue

Having multiple RadEditors on the same page, and trying the property "ToolProviderID" (to reuse the same floating tool amongst the different editors on the same page), causes a "javascript exception" on the client side.

URL of the Demo (Telerik Website)

https://demos.telerik.com/aspnet-ajax/editor/examples/toolprovider/defaultcs.aspx

Exception description

Uncaught TypeError: R.get_canAcceptTrackChange is not a function at c.RadEditor._initializeToolProvider (RadEditor.js:8239) at c.RadEditor.initialize (RadEditor.js:8297) at c.RadEditor.endUpdate (Telerik.Web.UI.WebRe…597d4b%3ab25378d2:6) at Sys._Application.endCreateComponents (Telerik.Web.UI.WebRe…597d4b%3ab25378d2:6) at Sys.WebForms.PageRequestManager._scriptsLoadComplete (Telerik.Web.UI.WebRe…97d4b%3ab25378d2:15) at Sys.WebForms.PageRequestManager.<anonymous> (Telerik.Web.UI.WebRe…597d4b%3ab25378d2:6) at Telerik.Web.UI.WebRe…597d4b%3ab25378d2:6 at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe…97d4b%3ab25378d2:15) at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe…97d4b%3ab25378d2:15) at Sys._ScriptLoader._loadScriptsInternal (Telerik.Web.UI.WebRe…97d4b%3ab25378d2:15)

Hi all,

I am following up with good news that the problem is fixed in the Latest Internal Build (Telerik_UI_for_ASP.NET_AJAX_2019_1_211_Dev|Trial_hotfix.zip) which precedes the R1 2019 Service Pack 1 release.
You can download the nightly build from here (press the the Internal Builds tab to locate the build).

The release notes are here.

Please let us know if you find any issues or side effects with the hotfix.

Best regards,
Rumen

Hello Bruce,

Thank you for reporting this regression and the detailed instruction!

The problem will be fixed in the upcoming R1 2019 SP1 release, due on Feb 20.

As a temporary workaround I would provide the following override that will fix the error:

<script>

var $T = Telerik.Web.UI;

var TOOLBAR_SELECTOR = ".reToolbar,.reToolBar";

$T.RadEditor.prototype._initializeToolProvider = function () {

var editor = this;

var toolProviderID = editor.get_toolProviderID();

var provider = toolProviderID ? $find(toolProviderID) : null;

if (!provider) {

return;

}

var getToolBarHolder = function (adapter) {

var wnd = adapter.get_window();

return wnd ? wnd.get_contentElement() : adapter.get_element();

};

var toolAdapter = editor.get_toolAdapter();

var providerToolAdapter = provider ? provider.get_toolAdapter() : null;

var providerToolBarHolder = getToolBarHolder(providerToolAdapter);

var providerToolBarElements = providerToolBarHolder ? $(providerToolBarHolder).find(TOOLBAR_SELECTOR) : [];

var providerToolBarsLength = providerToolBarElements.length;

var toolsFragment = document.createDocumentFragment();

editor.set_dialogOpener(provider.get_dialogOpener());

var contextJSON = provider.get_contextMenusJSON();

if (contextJSON && contextJSON.concat) {

editor.set_contextMenusJSON(contextJSON.concat([]));

}

var modulesJSON = provider.get_modulesJSON();

if (modulesJSON && modulesJSON.concat) {

editor.set_modulesJSON(modulesJSON.concat([]));

}

editor.set_toolJSON(provider.get_toolJSON());

toolAdapter.set_toolJSON(provider.get_toolAdapter().get_toolJSON());

var toolBarContent = getToolBarHolder(toolAdapter);

for (var i = 0; i < providerToolBarsLength; i++) {

$(providerToolBarElements[i]).clone().appendTo(toolsFragment);

}

$(toolBarContent).append(toolsFragment);

if (provider.get_spellCheckJSON) {

editor.set_spellCheckJSON(provider.get_spellCheckJSON());

}

if (provider.get_ajaxSpellCheckScriptReference) {

var ref = provider.get_ajaxSpellCheckScriptReference();

if (ref) {

editor.set_ajaxSpellCheckScriptReference(ref);

}

editor.set_links(provider.get_links());

editor.set_colors(provider.get_colors());

editor.set_fontNames(provider.get_fontNames());

editor.set_fontSizes(provider.get_fontSizes());

editor.set_symbols(provider.get_symbols());

editor.set_realFontSizes(provider.get_realFontSizes());

editor.set_snippets(provider.get_snippets());

editor.set_cssClasses(provider.get_cssClasses());

editor.set_cssFiles(provider.get_cssFiles());

editor.set_languages(provider.get_languages());

editor.set_paragraphs(provider.get_paragraphs());

editor.set_formatSets(provider.get_formatSets());

editor.set_enableUndoRedo(provider.get_enableUndoRedo());

}

</script>

<telerik:RadEditor RenderMode="Lightweight" ID="RadEditor1" runat="server"

I also updated your Telerik points for the inconvenience and the bug report!
