Hi,
I stepped into the same hole. Actually, my calling page uses an "object_type" parameter, so it's not possible to setup redirection pages as Lars proposed.
I believe that there is an _easy_way_ in this case: Including a hidden field in the form with return_url (which is "constant" for all columns) would do the job. However, it would be yet another parameter.
But in general I'm very disappointed with the list-builder. The idea is is nice, but the implementation is so obscure (you don't know what's happening until you check yourself in the source code) that I'm not going to use it much in the future. And I can't recommend to anybody doing so.
Bests,
Frank
