Agree with Alex on the last comment about proving that issues don't exist! I have one example of a trivial thing that I have found difficult to implement in all Tapestry versions I have used(3, 4, 5):
- A form with a loop in it. This is extremely common in the pages I make, and my mind always struggles when trying to find how this is done in the new Tapestry version. I never figured out a way to do it in 3 and 4 that made sense to me and looked correct. It also happened in T5. Maybe I'm stupid, but I really had to struggle hard to track down the details needed to implement this correctly, using encoders, initializing my form objects in the correct method in the correct way, and so on. I didn't find an example in the docs showing me the best practice for this (for me) very trivial and very common pattern.
