# Which issue does this PR close? Closes #703 # What changes are included in this PR? Fix a bug in the definition level calculation for fields nested within a struct and a list. When a list is empty or null in parquet the nested field gets a null value. However, in arrow, the value is simply missing. When serializing an immediate child of the list, the list offsets are used to calculate the correct definition level for its children, but it is not carried further to fields nested deeper (e.g., fields on a struct within a list). This (somewhat hacky) fix treats a struct within a list as if it were a list. # Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service.
