Hi Tim,
I can't offer a solution for this, but I'm having quite a similar task ahead of me. For the time being my extension I will need to migrate runs using extbase 1.3, but there have been some breaking changes introduced by 1.4 and I did't really dig into all the details. So just some comments: what you really want, is to pass your demand object to both instances - the filter and the list. You want to be able to alter the demand after it has been posted, don't you? What you could try, is to send your form to filter/show action and try fetching the demand via the request property (not sure if this will work, just guessing here). If this doesn't work maybe the signal slot/slot implementation could help (http://blog.foertel.com/2011/10/using-signalslots-in-extbase/) - but I didn't really dig into that, yet so I might be wrong here, too.
Hope one of these two work - any feedback or other ideas are well appreciated :)
cheers,
daniel
