Re: [I] bug: test `cast StructType to String` fails for duplicated col [datafusion-comet]

["comphead (via GitHub)" <gi...@apache.org>]

comphead commented on issue #2256:
URL: https://github.com/apache/datafusion-comet/issues/2256#issuecomment-3235337339

   This happens because of 
   ```
           if (struct.names.length != struct.names.distinct.length) {
             withInfo(expr, "CreateNamedStruct with duplicate field names are not supported")
             return None
           }
   ```
   
   Having commented this out I'm getting
   
   ```
   Caused by: java.lang.IllegalStateException: ArrowArray struct has 2 children (expected 1)
   ```
