Laurent - moved. Apologies for the delayed responses. I got diagnosed with hypothyroidism about 3 weeks, ago, apparently the neck surgery I had in November damaged my thyroid, so I've had no endocrine system all year, which dramatically affected my ability to work. I'm on thyroid meds now, and almost back to normal. Very glad to finally have a diagnosis, and that it's easily treatable. Busy catching up.
As for the 'behavior.select' stuff. We just haven't had time to look at the issues with it in repeat groups, so I really can't answer that question. That's pretty much what "WiP" is. Stuff we are experimenting with, but won't really know if it's entirely workable until we get further in to development. We'd like to make it work, as it does indeed make things a lot more usable.
Another issue is going to be triggering events when selections change. The problem being, our code is all Mootools based, but the new behavior fires jQuery events. So, for instance, at the moment it won't work as the "watched" element for a CDD, as changing the watched selection won't trigger the change event in the CDD code. And again, I can't really give an estimate on the time this will take, without actually trying out some workarounds.
