Is anyone else using the continuous build for 1.4.2 from November 2nd? I've tried all 3 of them, and the keyboard doesn't show up when I click a text area. I'm not sure if I'm doing something unusual in my application or if it's a known problem. Can anyone else confirm/deny?
Without providing your code, only you can confirm or deny whether you are doing something unusual in your application. ;p
However, try running the KitchenSink, and accessing the textfield/textarea scripts such as textfield.js, to see whether the keyboard appears.
Thanks for the suggestion, it helped me find the cause. I'm using the implementation described in this post for adding a "Done" button toolbar to the keyboard. The animation specifies zIndex=4, which seems to cause the keyboard to be invisible in the continuous builds.
