Upgrading to Rails 2.3.8 from 2.3.2 has broken views in my application.
[snip]
Rails 2.3.8 is a stepping stone to Rails 3 with lots of deprecation warnings and some actual changes. And not all Gems and plugins are compatible with it. I suggest migrating from 2.3.2 to 2.3.5 first. Then try going to 2.3.8. And expect problems in both your code and others' code. I.e., allocate time to do the conversion and accept that you may have to wait for compatible gems/plugins to be available. (Or figure the necessary patches and submit them to the author.)
