Sorry. "Bad" is a strong
word and I use it loosely all too much. I'll try to do better with it around here.
To my chagrin, Google did not give me any results either.
DynaForms are a convenience, but you giving up control for that convenience. When starting out this is not a big sacrifice. But with more complicated application scenarios the lack of control can become a bigger inconvenience than anything. Not to mention restarting your server every time you add a field or validation to a form is annoying.
If I had a very very simple app that I knew I could write the frontend in little time I would use DynaForms. They are not inherently evil.
Sorry for not putting more thought into my post.
