redirect requested, response already committed

[Michael Burschik <Bu...@lotto-berlin.de>]

I created a database browser based on the bluesunrise tutorial example.
"Edit" links for the individual items link to another portlet on another
page. The edit form works as expected, except for the fact that I can not
return to the database browser with a redirect. The only clue I found in the
jetspeed log is the notice "redirect requested, response already committed",
which I do not understand.

This question, or a similar one, seems to have been raised once before in
March, but I failed to find an answer to the inital post.

Any elucidation would be warmly appreciated.

Regards,

Michael Burschik

AW: redirect requested, response already committed

[Michael Burschik <Bu...@lotto-berlin.de>]

As far as I can see, the method doCancel is called as expected. This in turn
calls returnToBrowser, which uses rundata.setRedirectURI to request a
redirect. But then, the view processor starts processing news-form, which is
the template associated with NewsFormAction, rather than processing
news-portlet, which is the template associated with NewsBrowser. Has the
redirect failed?

That much was obvious. But if I use an action method like doCancel, then
buildNormalContext isn't called. Or is it?

Yes, the tutorial works. And yes, I have looked at the code there. In fact,
I pretty much copied the example provided by the tutorial and modified it
slightly. Apparently, one of these slight modifications horribly broke the
tutorial example. And yes, I would have read the f*ing manual if there was
one.

Sounds like you are trying to redirect from within the build normal 
context method, and not the action.
You have to redirect in the action phase, its too late in the 
getContent phase.

Anyway it does work in the tutorial, right?
I would suggest looking at the code there....

See TutorialCoffeesAction, the returnToBrowser method, called from the 
doUpdate action
