Turns out this is actually not a bug where the underlying bitmap is null, but we need to overwrite the dictionaryBuilder to use the idxBuilder's `IsNull`. ```go func (b *dictionaryBuilder) IsNull(i int) bool { return b.idxBuilder.IsNull(i) } ``` I'll update this PR tomorrow. -- This is an automated message from the Apache Git Service.
