|Product||Progress® Telerik® Reporting|
|Report Viewers||HTML5-based Report Viewer|
The error message appears in the browser's console when running a web application with the HTML5 Report Viewer.
The HTML5 Report Viewer is an HTML\CSS\JS client-side widget. The viewer requires a link to jQuery v1.9.1. or above, which may be in contradiction with other components loading jQuery on their own.
Verify the page loads jQuery of version 1.9.1 or above only once.
If you use Telerik UI for ASP.NET AJAX RadScriptManager, it loads its embedded version of jQuery. You can use the external link to other jQuery file by setting the EnableEmbeddedjQuery property of RadScriptManager to false.
