I try to use wicketstuff-push with wicket 1.4-m3, but I can't get it to
work.
I have checkout wicketsuff-dojo (and examples), modified them to use
jetty 7.0.0pre2 and wicket 1.4-m3 and it is OK.
Then I co wicketstuff-push and examples, modified them to use the same
version of wicket (some errors to correct) and jetty, but I can't get it
to work.
The examples "A chat using simulated channel based on polling" and "A
chat using simulated push based on polling" are working (polling is OK)
but I get an NPE when I really use CometdBayeux with test "Basic Cometd
tests" :

It seems that the "Id" param is null...(from the 7.0.0pre1 sources of
cometd : the 7.0.0pre2 did not exists (1))
I didn't find how to correct this... I have search deeply in wicketpush
and wicketdojo, and it seems to came from a javascript in
wicketstuff-dojo.. I realize that wicketstuff-dojo use dojo 0.4
internally, (I'am not a dojo expert, but the last version seems to be
1.1.1)...
So here are my questions :
- did anybody successfully manage to use wicketstuff-push with jetty
(6.1.11 or 7.0.0pre1)?
- wicketstuff-push is it alive? last commit was 15/11/07 ...
-and if not what do you use to do reverse ajax with wicket?
Note : I already used cometd-bayeux in a Spring MVC Application, so
maybe the solution is to use cometd at "low" level ie. with no
integration with wicket...?
Thanx,
1 : sources of cometd-bayeux artefact (only in version 7.0.0pre1):
