created issue #1

Dec 17, 2018 02:24PM

Component used: Room
Version used: 1.1.0
Devices/Android versions reproduced on: all

I have two classes:
parent class - parent.kt
child class - child.kt

and standart dao.

But allways return data with null value - contactDetails. In generated code i will see next:
```
//...
final ContactDetails _tmpContactDetails;
if (! (_cursor.isNull(_cursorIndexOfCountryCode) && _cursor.isNull(_cursorIndexOfPhoneNumber))) {
final String _tmpCountryCode;
_tmpCountryCode = _cursor.getString(_cursorIndexOfCountryCode);
final String _tmpPhoneNumber;
_tmpPhoneNumber = _cursor.getString(_cursorIndexOfPhoneNumber);
_tmpContactDetails = new ContactDetails(_tmpCountryCode,_tmpPhoneNumber);
} else {
_tmpContactDetails = null;
}
_item = new ShareAccount(_tmpShareId,_tmpEntityId,_tmpUserId,_tmpOwnerId,null,_tmpCreatedAt,_tmpModifiedAt,_tmpAction);
/....
```
that is, regardless of the value of _tmpContactDetails, it will eventually be set to null.

Accepted by ya...@google.com.

The testing artifact (work-testing) will have the ability to trigger initial delays and period met signals in alpha09. You should use this to simulate any testing you need.

Wau, that was incredibly fast, thanks!

yes, ready:

For ChildSecond in generated class SecondDao_Impl (in the case FirstDao_Impl is not a problem) i see next code:
final ContactDetails _tmpContactDetails;
if (! (_cursor.isNull(_cursorIndexOfPhoneNumber) && _cursor.isNull(_cursorIndexOfCountryCode))) {
final String _tmpPhoneNumber;
_tmpPhoneNumber = _cursor.getString(_cursorIndexOfPhoneNumber);
final String _tmpCountryCode;
_tmpCountryCode = _cursor.getString(_cursorIndexOfCountryCode);
_tmpContactDetails = new ContactDetails(_tmpPhoneNumber,_tmpCountryCode);
} else {
_tmpContactDetails = null;
}
_item = new ChildSecond(_tmpEntityId,_tmpSomeField,null);

That is, the problem is exactly the same

When child class has empty constructor, field is set to null

please - Is there any non-AndroidX room library that this bug is known to a) occur in or b) not occur in?
