Repeated does work with enums.
Can you give a bit more context, e.g. what is the language you are creating
code for, and what exactly does the "serialization error" manifest (error
message or error code).
How do you serialize and deserialize the data ? A common problem is to not
deal with NUL bytes properly in the stream, i.e. if you interpret something
as a NUL-terminated C-string somewhere in the process it might look like a
too short buffer.

[protobuf] "repeated" elements
I have the following message definition in a proto file which is causing a
*serialization
error*:
message Request {
repeated LanguageType LanguageList = 1;
}
enum LanguageType {
English = 0;
German = 1;
Spanish = 2;
}
*If I make the following change:*
message Request {
repeated LanguageTypeList LanguageListParam
= 1;
}
message LanguageTypeList {
optional LanguageType LanguageList = 1;
}
enum LanguageType {
English = 0;
German = 1;
Spanish = 2;
}
can anyone explain what is happening? does *repeated* *NOT WORK* with*
enums*?
thank you
