For my application, I will need to allow users to enter their own (essentially random) e-mail addresses. The Palette component seems to require a pre-defined set of available options, which unfortunately does not meet my particular requirement. So I will continue work on my own custom property editor.
I discovered that the BeanEditForm guide page almost completely neglects to discuss PropertyEditContext objects, knowledge of which seem rather critical to fully understanding how to create a custom property editor. I found some discussion of PropertyEditContext at the following wiki topic.
http://wiki.apache.org/tapestry/Tapestry5HowToCreateAPropertyEditBlockI believe I now have the general idea and will start working out the details by experimenting in code.I may yet have questions, but at least I know where I'm headed now. Many thanks for pointing me in the correct direction.

If it is notenough, post yourr doubts here and we'll try to help you. ;)I am working with a directory services database via LDAP and it would be extremely helpful if I can mange to enhance BeanEditForm and BeanDisplay to handle LDAP entries where a property (LDAP attribute) may have multiple values. To be more specific, I want to create a property editor for the String[] type. At the moment, I just want to display String[] properties using the BeanDisplay component, but I can already foresee a need to be able to fully edit a String[] property (including adding / removing values from the array, using AJAX to add/remove fields to the form).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). The BeanEditForm guide previously mentioned tells you how to do it. -- Thiago H. de Paula Figueiredo Independent Java consultant, developer, and instructor http://www.arsmachina.com.br/thiago --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
