I am trying to allow iFrames to be added into the editor without any luck so far. I have added the following to TinyMceConfig.config

iframe[src|width|height|name|align]

So my validElements node in the config file looks as follows:

  <validElements>
    <![CDATA[+a[id|style|rel|rev|charset|hreflang|dir|lang|tabindex|accesskey|type|name|href|target|title|class|onfocus|onblur|onclick|
ondblclick|onmousedown|onmouseup|onmouseover|onmousemove|onmouseout|onkeypress|onkeydown|onkeyup],-strong/-b[class|style],-em/-i[class|style],

dd[id|class|title|style|dir|lang],dl[id|class|title|style|dir|lang],dt[id|class|title|style|dir|lang],object[classid|width|height|codebase|*],
param[name|value|_value],embed[type|width|height|src|*],map[name],area[shape|coords|href|alt|target],bdo,button,code,iframe[src|width|height|name|align]]]>
  </validElements>

Any ideas what I am doing wrong or missing?
