Tapestry has a great mechanism to switch assets based on the user's
language. Now I would like to have something like that based not on
language but the user's tenant (the system is multi-tenanted).

I tried to reproduce that (being the curious person that I am ;-) ),
but the constructor of a page is called only once on my machine - just

If you want to analyze I suggest adding

zone.getBody():

Hope this helps

Your event handler returns a JSONArray which is probably not what you
want.
You wrote initially that you would like Tapestry to re-render your

Hi George,

to go - you would either detach the entities or use some sort of

Another way to go is to put the wizard into a single Tapestry page and

Hi all,
Tapestry has a tree component, but it focuses on one specific way of
using trees.
In the project I am currently working on, we would like to use trees
in a different way. So I got down and started creating a tree
component, open sourcing it:

Sorry, my mistake - I replied without really thinking...
I was thinking about a similar phenomenon when a loop contains links
that refer to the loop variable, e.g. as their context. Then you need
to use 'deferred="true"' with the links.
As Lance wrot

Your encoder returns null both ways - that is probably the cause for
your NPE.
It is responsible for storing (and retrieving) the collection elements

It is straightforward to build a component that embeds a single body,

Using the context attribute is the way to go. It's plain 'context' and
not 't:context', though.
The context must be a primitive (or encoded as a primitive), so I
would recommend you start by passing only the position

I want a JavaScript event handler to programatically submit a form.
This works well using form.performSubmit() (I want Tapestry's AJAX
submit).
The tricky part is that the form being submitted is part of the zone
that is being refreshed by the submit,

As I see it, it boils down to one of two cases.
