There were several customers reporting the same problem with the UIX LOV (UIX component messageLovInput) in JDeveloper 10.1.2:
- the LOV wasn't returning the selected value in the UIX page the first time it was invoked;
- however, it was working correctly the next times a LOV was invoked in the same page.
