Cannot enter null value in class

Question

I have a fragment that I want to reuse. Its functionality is the same, only layout changes

I use roboguice to inject id views into variables

I added this view, for example:

@Nullable
@InjectView(R.id.edtEventLocationAddress)
private EditText edtEventLocationAddress;

this view may or may not be present in this layout i, presented in the onCreateView method

that's why i put on it @Nullable

however, when I launch the application, with a layout that does not have this representation, I get

java.lang.NullPointerException: Can't inject null value into class 
com.myapp.CreateEventPageFragment.edtEventLocationAddress when field is not @Nullable

What do I need to do so that roboguice allows me to reuse fragments and only change their presentation?
