This is how tabView
works. Here are the relevant issues from the PrimeFaces tracker:
- http://code.google.com/p/primefaces/issues/detail?id=3423.
- http://code.google.com/p/primefaces/issues/detail?id=4143
As you can see the first one is marked as WontFix. The second is a duplicate but at the end you will see another workaround.
If you read that thread carefully you may notice that some workarounds still exists. Try one of them if you are forced to use tabView
. Also consider using PrimeFaces - Wizard if you want to use inputs in different tabs.
