I am trying to use the Content Editor and in particular the 'Edit HTML Source' button to input some HTML directly into the content.

However when I enter the HTML and then look at what has been saved - certain sections are missing. An example of a piece of code I am trying to insert is as follows:

<img CLASS="imagelinkpointerout" onmouseover="this.className='imagelinkpointerover'" onmouseout="this.className='imagelinkpointerout'" src="/themes/tutorial/images/links/test_logo.gif"  width="170" height="106"  ALT="Test Logo">

The resultant code is:

<img class="imagelinkpointerout"   src="/themes/tutorial/images/links/test_logo.gif" border="0" width="170" height="106" ALT="Test Logo">

The onmouseover="this.className='imagelinkpointerover'" and onmouseout="this.className='imagelinkpointerout'" have been dropped for some reason.

I am confused as to why this is happening. Any suggestions on how I can resolve this would be appreciated. :-)

btw - I am running SilverStripe-v2.3.0-rc4

The TinyMCE Configuration strips out things like onmouseout. You will have to edit the config settings in cms/javascript/tinymce.template.js under the 'allowed_elements'

Thanks for the pointer :-)
Having done some additional reading on TinyMCE, I assume by 'allowed_elements' that you mean 'valid_elements'.
However in the cms/javascript/tinymce.template.js file in SilverStripe-v2.3.0-rc4 there is no 'valid_elements' line. I t seems to have been removed since the SilverStripe-v2.2.3 version - I can't (at the moment) find any mention as to why this should be.

Anyway, I followed these recommendations:
http://doc.silverstripe.org/doku.php?id=tinymce&s=tinymce
http://wiki.moxiecode.com/index.php/TinyMCE:Configuration/extended_valid_elements

and added these lines:

valid_elements : "*{*}",
extended_valid_elements : "img[class|src|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name]"

Note: The '{' & '}' above are open and close square brackets - had to substitute as Code block incorrectly reformats it :-|

Whether the 'extended_valid_elements' line is necessary given that I have selected all elements, I don't know?

However, It still isn't accepting the onmouse over tag :-|

This is becoming frustrating, so any suggestions as to what I am doing wrong would be gratefully received :-)
