TinyMCE plug-ins not firing in Composite C1 - c1-cms

Question

I've created a new plug in as I could not find one that actually "works", hoping that if I do it from scratch it might fire.
The plug-in simply wraps selected text with a mailto: link.
I've added the plug-in to the includes file, as per the following response on a previous question: http://bit.ly/vGyQlE however, it's not working.
I've gone into the localization directory, identified the Composite.Web.VisualEditor.en-us.xml as the file that handles the localization, added my entry under :
<string key="ToolBar.ToolTipMailTo" value="Mail To" />
But when I hover of the "blank" block where the menu item should appear, it returns (?). This is the first part where I picked up on something wierd. When you actually click on where the item should appear, nothing happens. So, I can't assume that the click event has got to do with an image, I re-wrote the command to return an alert, when clicked:
tinymce.create('tinymce.plugins.MailTo', {
init : function(ed, url) {
ed.addButton('mailto', {
title : 'mailto.mailto_desc',
cmd : 'mceMailTo',
image : url + '/images/mailto.gif'
});
ed.addCommand('mceMailTo', function() {
var selectedText = ed.selection.getContent({format : 'text'});
var MailToLink = "alert(" + selectedText + ");";
ed.execCommand('mceInsertContent', false, MailToLink);
});
I've added the "mailTo" element to visualeditor.js:
plugins : "...,paste,lists,mailto",
And ensured that the "mailto" plug-in is situated under the plug-ins directory for tiny_mce. I've gone as far as to clear my cache several times, but nothing? Can it be this difficult to add new plug-ins to tiny-mce in Composite?

Answer 1

1) Composite C1 does not support internal tiny_mce buttons
Do you add button to editor?
In file Composite\content\misc\editors\visualeditor\includes\toolbarsimple.inc add
<ui:toolbargroup>
<ui:toolbarbutton cmd="mceMailTo" tooltip="Mail to" image="${icon:paste}" isdisabled="false" />
</ui:toolbargroup>
2) Do you write valid plugin code?
(function () {
tinymce.create('tinymce.plugins.MailTo', {
init: function (ed, url) {
ed.addCommand('mceMailTo', function () {
var selectedText = ed.selection.getContent({ format: 'text' });
var MailToLink = "alert(" + selectedText + ");";
ed.execCommand('mceInsertContent', false, MailToLink);
});
}
});
tinymce.PluginManager.add('mailto', tinymce.plugins.MailTo); })();
