Is there a WYSIWYG editor for Tapestry, or an IDE plugin?
Currently, no WYSIWYG editor is available for Tapestry; however, the design of Tapestry allows existing editors to work reasonably well (Tapestry additions to the HTML markup are virtually invisible to a WYSIWYG editor). Spindle is a Tapestry plugin for the excellent open-source Eclipse IDE. It adds wizards and editors for creating Tapestry applications, pages and components. All of the various ide plugins can be found here.
