The Editor button to insert a JoomDoc document was not showing. I checked the plugin and note that it is missing the
$button->set('class', 'btn');
in the joomdoc.php file (in plugins\editors-xtd\joomdoc).

Adding this line restores the button and it now works.

Hello, thanks for the information. What Joomla version it is?

I've got Joomla 3.3.0 running.

OK, thanks.
