Object in Flash scope is not available after redirect

by

The Mojarra’s implementation of the JSF2 Flash scope had a lot of problems. Most of them were resolved with every new Mojarra release. Currently, with the latest Mojarra version, the 2.1.6, there’s as far as I know still only one major open problem: it won’t work if you redirect to a different base path. See also the (currently) last comment in the long discussion in issue 1751.

Right now, you have basically the following options:

  1. Forget using Flash when you need to redirect to a different base path. Use a request parameter instead or try to simulate the flash scope with a custom cookie.

  2. If possible, reorganize the folder structure so that you don’t need to redirect to a different base path when you need the flash scope to survive.

  3. Try MyFaces instead of Mojarra. Maybe it does it better with regard to flash scope.

Update: as per issue 2136, the last open problem of Flash scope not being available after a redirect on a different path is solved in the shortly upcoming Mojarra 2.1.14. So with this version, all Flash scope related problems discovered and open so far
should be solved and closed.
