@liyafan82 seems working correctly in all cases if we add `writer.startList` and `writer.endList` together with `vector.setNull`. I have refactored `writeListVector` function in test to make it more universal. May be we should add `protected FixedSizeListVector vector` in `UnionFixedSizeListWriter` getter and/or cache `FixedSizeListVector.getWriter` output (in current version new writer is created on every invocation). This allows `writeListVector` ans similar methods to have only vector or only writer parameter with keeping new functional. Cross-test with C++ is again made in [my project](https://github.com/Kopilov/Arrow_FixedSizeListVector_ZeroWidth/runs/1403388868). But where are cross tests made in Apache Arrow itself? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
