[GitHub] [beam] kennknowles opened a new issue, #18348: @DefaultCoder annotation should work with Create

kennknowles opened a new issue, #18348:
URL: https://github.com/apache/beam/issues/18348

   From user@beam.apache.org:
   
   "My class is declared as follows:
   
   @DefaultCoder(SerializableCoder.class) public class Data<DataT extends BaseData\> implements Serializable {
   
   and it fails like this:
   
   Caused by: org.apache.beam.sdk.coders.CannotProvideCoderException: Cannot provide coder based on value with class my.project.Data: No CoderFactory has been registered for the class."
   
   It seems like this should work, though Create's value-based coder inference has more limitations and safety issues than usual coder inference. To investigate.
