I encountered similar problems with the WYSIWYG editor rewriting attachment
or image URL's and causing errors.

In your case wouldn't the problem be solved by adding your macro to the list
of macros that
the editor won't touch? Then the macros would never expand, and the
foolishness inside tiny_mce that garbles all URL's into utter uselessness
would never get invoked. The other approach is what
i did, which is to side-step thhe URL-garbling in the first place.

In my case, I solved it by setting up a special macro to launch the WYSIWYG
with the correct parameters that appear to prevent this problem, along with
a JavaScript hack that overrides the bad URL-rewriting behavior.  Things
work fine as long as references are "local" during editing/authoring in the
wysiwyg. After "save" or "publishing" , (if that happens to move the
location of attachments, etc), as long as references remain local, then
things continue to work smoothly.

The issue is that no amount of fiddling with setting of tiny_mce parameters
relative_urls:
or convert_urls: affects the bad wywsiwyg behavior. The only thing that
seems to work
is overriding the javascript function that causes all the bad behavior.
There's ways of giving an additional parameter to tiny_mce to point it at a
different convertURL() function, but since the parameter is not used
consistently, it actually doesn't work. So at least for my 1.3.X based
experiements, I was only able to achieve succcess w/ the tiny_mce wysiwyg by
adding
the following at the bottom of any form/document that uses the wysiwyg in
this way:

/*
 * HACK: Tell TinyMCE to leave-alone the URL's ... they are fine as-is.. as
relative links
 * during edit in AssetTemp/xxxxxxx, and as permanent links in
$wysi_publishSpace on save
 */
tinyMCE.convertURL =3D function(url, node, on_save) { return url; };

(above in context:
http://fisheye2.atlassian.com/browse/~raw,r=3Dtrunk/xwiki/xwiki-products/curr=
iki/trunk/wiki/src/main/resources/CreateResources/CurrikiStandardLessonPlan)

Note the parameters I pass to tiny_mce are setup in the macros below:

(from
http://fisheye2.atlassian.com/browse/xwiki/xwiki-products/curriki/trunk/wiki/=
src/main/resources/CreateResources/StyledMacros?r=3Dtrunk)
##
## Fire up the WYSIWYG editor. See
http://next.dev.curriki.org/xwiki/templates/textarea_wysiwyg.vm
## This "inlines" #template("textarea_wysiwyg.vm") as it needs to customize
the behavior
## Note that this makes reference to vars $xwiki, $request and is to be
added at the end of
## forms to enable wysyiwyg editor javascript.
##
## Must be called in sequence
## #curriki_wysiwyg_loader_preamble()
