Sorry to jump in here Chris... Jan not exactly sure what you are doing
since you haven't shown your code, but the exception is telling you "the
response has been committed" , which means you are trying to modify a
Response that is being processed, i.e.: it is read only. If you
interrupt the response, for example with a redirect, then try returning
true.
if(interruptHere)){
response.sendRedirect("/login");
return true;
}
return false;

Hi Chris,
Thank you. As a matter of fact I used your wiki entries as my main
inspiration. So what I do now is:
use: "before:RootPath" for the contributation and
return 'false' on the dispath for '/login and '/assets/'
This works but in the background the following stuff is logged
(To be more precise I'm using an ASO in my dispatcher)
Question is: should this worry me?

Hi Jan,
The first 2 paragraphs of this article cover what you want to do:
http://wiki.apache.org/tapestry/Tapestry5HowToCreateADispatcher
Included also are relevant links to javadocs, as well as references to
the TapestryModule, where you can see how it influences dispatcher ordering.

Hi,
Just posted a question on dispatcher chain - but I think the subject
line was way to unclear - so sorry for asking the question again.
I want all of my pages (also the one that is shown when I access root
context without anything - so no '/start') to be passed thru my
dispatcher. How can I do that?
