Have you taken a look at the Palette component? It looks like it it already implements what you need: http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Palette.html . It, together with a custom DataTypeAnalyzer, one view block (for BeanDisplay) and one edit block (for BeanEditForm/BeanEditor).
