Orbeon Forms has supported rich text editing for the longest time, leveraging the YUI 2 RTE. However, depending on your situation, the RTE isn't always the best editor. For instance, it doesn't support <p> and instead uses <br>, by design. Also, it can't be use on iPads and iPhones, despite iOS 5 now supporting HTML5's contentEditable. For this reason, we created a new component, which uses the TinyMCE WYSIWYG editor, with the thebigreason skin.
For more details, see the TinyMCE component documentation. Our thanks go to Teleflex, who sponsored the development of this component, as well as Florian Schmitt, who contributed a first implementation.
