The ONLY useful resource on LiveCycle/PDF forms I've yet managed to find is:
Stefan Cameron on Forms
But I'm finding it increasingly bizarre that Adobe don't openly publish this kind of information - why isn't there an MSDN-style resource that we can all use quickly and easily?
I don't want to sound ungrateful, but the Adobe user-to-user forums just aren't detailed enough to be really useful. When you're developing a solution you need answers right away, not hours, days or even months later. Plus, the same questions keep coming up again and again, with different people answering them at different times.
Seriously, the lack of available info is extremely frustrating.
