Custom Property Editor for String Array
Before I go banging my head against a wall for too long, is it
possible to create a custom property editor to handle a complex (multi-
valued) property?
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).

In this case, Tapestry does not have such a component. I guess you can
implement it with a little of Javascript, something Prototype will help.

You're right. Please file a JIRA for a documentation improvement. ;)

You're welcome!

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/Tapestry5HowToCreateAPropertyEditBlock
I 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.

Yes! :) There's a guide here:

enough, post yourr doubts here and we'll try to help you. ;)

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.
