TinyMCE is just trying to help!
I have no solution for you - I've battled TinyMCE before with little luck - but I would expect that just opening a resource in the manager with TinyMCE running and then saving the resource would reproduce the problem - TIny replaces automatically anything that it thinks should be an entity (like
) similar to way if I try to type ; ) without a space this forum software gives me a smilely!
So if I'm right any time someone edits a resource they will also break the links that are coded with modx tags
in that resource
I can't imagine that this is correct behaviour, I've never seen this before although as I say I have fought TinyMCE ... such as the page that had a
on it and every time the resource was edited Tiny would change it to
which does not work!
... or Tiny's habit putting p tags around things just because one presses the return key
enough rambling - hope you figure out your problem - there are settings for tiny in the manager but apart from adding special tags (a tag with a class for example) I've not had much luck customizing Tiny.
