PDF Exports with Tables and ContentFilter

[Sergey]

I am using the built in PDF export functionality of RadEditor, and there's a need to have a table. I've found that because of some issues between the PDF export tool, that a filter needs to be run to add some tags, as per http://www.telerik.com/community/forums/aspnet-ajax/editor/html-to-pdf-shows-blank.aspx and http://www.telerik.com/community/forums/aspnet-ajax/editor/export-to-pdf-doc.aspx

However, when I added the JavaScript code, I get an error on the line: 

MyFilter.registerClass('MyFilter', Telerik.Web.UI.Editor.Filter); 

The error being 'Telerik is not defined'. I'm not entirely sure if there is an extra requirement to use the registerClass method. There are other Telerik controls on the page, and they do not throw any errors and work as expected without this line of code being there. 

Thanks for any suggestions.

And of course figured it out shortly after, the filter JS was executing before the Telerik WebResource file was fully loaded. Fixed with some jQ.
