Folks,
Using extended tapestry crud on beta-22
I have a simple model object called Year.JAVA... it implements a startYear and
endYear... nothing major see below.
I didnt create any custom edit/add/show/collection pages for this. So it fits
into the same framework as-is.
I got a standard Edit.JAVA which implements tapestry-routing... see below...
nothing customized... this is as-is too
Everything works... except for CANCEL... it gets lost in never never land.
Everytime I ADD or EDIT with a subsequent CANCEL, it is suppose to go back to
the Show.JAVA an dinstead it goes off to some ... well it takes the ROUTE atop
the edit page for that model and operates that instead of operating the ROUTE
to get back to the Show.JAVA page
First I do a show on the model with Show.JAVA page
url processed for this is as follows
"/psi/show/year/1"
I open up a year model into edit page and the url is as follows
"/psi/edit/year/1"
the problem is in this cancel() routine... below
then I attempt a cancel with logic below HOPING I will be brought back to the
Show.JAVA page
@At("/{0}/{1}/edit")
@OnEvent("cancel")
Link cancel() {
return pageRenderLinkSource.createPageRenderLinkWithContext(Show.class,
passivate());
}
after this is executed on the Year.JAVA model my REST url is as follows
"/psi/year/1"
when I am suppose to get
"/psi/show/year/1"
I am unable to debug this.. any hints ? Appreciate any help
Best regards
and thanks... KEN
