I noticed another developer is having the same issue at the bottom of this question: http://developer.appcelerator.com/question/5881/titanium-developer-crash-with-titanium-sdk-110. When I go to a text field and click on it, the keyboard pops up correctly. After I type in some text and click the return key, nothing happens.
it's a regression issue - seems to be related to text fields within scroll views. text fields in normal windows and views seems to work properly. we will fix this for the next release. in the meantime, you can trap the 'return' event from a text field and call blur() when you receive it.
