kawadakk opened a new issue, #7165:
URL: https://github.com/apache/arrow-rs/issues/7165
**Describe the bug**
`RowConverter::convert_rows` panics when decoding rows of type
`List(Dictionary(Int32, Int32))`.
**To Reproduce**
```rust
#[test]
fn test_list_of_primitive_dictionary() {
let mut builder =
ListBuilder::<PrimitiveDictionaryBuilder<Int32Type,
Int32Type>>::default();
builder.values().append(2).unwrap();
builder.values().append(3).unwrap();
builder.values().append(0).unwrap();
builder.values().append_null();
builder.values().append(5).unwrap();
builder.values().append(3).unwrap();
builder.values().append(-1).unwrap();
builder.append(true);
let a = Arc::new(builder.finish()) as ArrayRef;
let data_type = a.data_type().clone();
let field = SortField::new(data_type.clone());
let converter = RowConverter::new(vec![field]).unwrap();
let rows = converter.convert_columns(&[Arc::clone(&a)]).unwrap();
let back = converter.convert_rows(&rows).unwrap();
assert_eq!(back.len(), 1);
back[0].to_data().validate_full().unwrap();
assert_eq!(&back[0], &a);
}
```
```

Expected infallible creation of GenericListArray from ArrayDataRef failed:
InvalidArgumentError("[Large]ListArray's child datatype Int32 does not
correspond to the List's datatype Dictionary(Int32, Int32)")
```
**Expected behavior**
Not panicking
