David Janicek updated BEAM-10292:
---------------------------------
Description:
*DefaultFilenamePolicy.ParamsCoder* uses simple *StringUtf8Coder* for
encoding/decoding *DefaultFilenamePolicy.Params*'s *baseFilename* and therefore
looses information whether *Params.baseFilename* resource ID is file or
directory.
The result is that it's effectively preventing user to define directory as
*baseFilename provider* when using dynamic destinations because after
deserialization it's translated to file.
Solution is easy - use *ResourceIdCoder* for encoding/decoding.
