I've since discovered that you also can't use the above workaround with tinymce mode set to mode : "exact" But, it seems there is a superior work around.. still a bit of a pain, but it works. Call the following on submitting the form. function updateValue() | { | tinyMCE.execCommand('mceRemoveControl', false, 'idofmyeditorregion'); | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074105#...
