I have managed to get TinyMce working with seam remoting, it just the component flickers whenever the form is reRendered. I will have a look at Emforge article.
Mo, http://www.emforge.org activelly used tinyMCE for editing wiki-pages and all other text information.
It is worked quite fine with RichFaces.
We still did not prepeared any documentation about it - hope to do it soon. Anyway it is opensource - so, feel free to get sources and use them as example.
