Hello,
there is a bug report for this issue:
https://issues.apache.org/jira/browse/TAP5-2602. I met this same issue
when porting from Tapestry 5.2 to 5.4.
I solved it with a hack. I replaced the tapestry t5/core/dom prototype
module file and added code to the ElementWrapper.trigger method. I
re I could choose between the coffeescript documentation or Javadoc
documentation. This seems to have been replaced with a direct link to
the Javadoc documentation. Where can I find the link to the coffeescript
documentation? It has been very useful. A direct link would also be fine.
