Hello Hugues,

I encounter exactly the same problem, and I wonder if you found a 
solution for it (that seems quite common...) ?

I have a form, and I would to update some data/field in it when some 
other data or option are selected. I search with zone, formfragment, but 
each time I get a " No object of type 
org.apache.tapestry5.services.FormSupport is available from the 
Environment. "
So, does somebody ever succeed in something like that ?

Thanks in advance,

So, no real interest in the community for this?

In general, I find the Zone concept a bit hard to nail down. I have gained
som experience in T5 now, and have made several attempts at making my Zone
demo page work like expected, but I still haven't made it happen. My debug
path so far:

1. Created a zone, and a listener that returned nothing. Made my zone go
blank. Obviously because the listener needs to return the component that
should be displayed in the zone.
2. Put an Any component in the zone, containing one form element. Got the
error described in this thread.
3. Removed form elements in Any component. Works nicely now, with fading and
everything. But no use for me :)

The main impression of T5 so far is that everything I try just works on my
first attempt. Huge difference from struts and earlier versions of Tapestry.
JSPs NEVER work on my first attempt. The zones are the first exception to
this.

Am I supposed to use some other technique for refreshing parts of my form
with XHR when a link is clicked (or some other client side event).
FormFragment is mentioned here, it sounds like the solution to my problem,
but can it be combined with AJAX?

Hi Francois,
The solution I found is .. not to use zones :)

Unfortunatly I went throught the same path as yours by looking at
FormFragments, but without any success...

Thanks
Hugues
