[T5] Zone within Form (component dynamically adding form components)

[Peter Beshai <pe...@gmail.com>]

I have a component that will be used to edit a list in a form. It has the
ability to add/remove items from the list and when it adds one, fields to
edit the new item become available. I would like to have the add action be
asynchronous so that any other edited fields in the form do not get reset
when the user clicks add, so I figure I will need to use the zone component.

I thought it would make sense for the component itself to provide a zone
that it will handle updating all on its own, but when I try having a zone
inside a form I get (when I click add):

[ERROR] RequestExceptionHandler> Processing of request failed with uncaught
exception: Render queue error in
SetupRender[test/Sandbox:listbeaneditor.beaneditor]: No object of type
org.apache.tapestry.services.FormSupport is available from the Environment.
Available types are org.apache.tapestry.PageRenderSupport,
org.apache.tapestry.ValidationDecorator,
org.apache.tapestry.internal.services.ClientBehaviorSupport,
org.apache.tapestry.services.Heartbeat.


It seems to work when I have a zone around the form and pass that zone as a
parameter to the component, but I would ideally have this component used as
a block in AppPropertyEditBlocks, which I don't think allows me to pass in
the zone as a parameter. Plus, by having a zone around the entire form, the
entire form gets refreshed instead of just this one section.

Does anybody know a solution to this problem?
