TinyMCE textarea appears inside the editor

I'm applying开发者_StackOverflow tinymce to a textarea using jquery.tinymce. but i'm having a problem where the textarea is also appearing inside the editor when it should have been replaced by it instead.

Remove all the ID attributes of "textarea" elements.
This will fix appearing a textarea inside the editor.

think in the end i was giving the textarea the same id as another element on the page. A bit of tweaking later it was fixed.
