If data binding is used it is common that the property is null at first. With older versions this wasn't an issue but a recent commit changes the behavior and an exception is thrown for such scenarios:
This commit breaks things: 6638c67#diff-913f8d5c561cd24bc687f40058980ae2

What I did was rolling back to version 3.4.0.100 that doesn't yet contain this change.

Edit: As it looks this also has been reported already here: #28
