Problem with BaseModel and reference to other BaseModel class

[Gahgah]

Hello,

I'm currently having a problem with to Classes which both extend BaseModel. CustomerDTO has an Attribute of the type StandortDTO (I've attatched both classes). Setting the StandortDTO works fine (I added a Screenshot which show an instance of CustomerDTO where the Standort DTO has been set.
The problem I'm currently not able to solve is that my RPC calls fail. I get a SerializationException without any message or stacktrace.
Any help would be great.

Thanks in advance.
Best regards
Jan

Make sure your RPC code somewhere references the StandortDTO class. This can be for example an unsed field in your CustomerDTO class:

private StandortDTO unusedStandortDTO;

Danke

I thought StandortDTO in my method signature would be enough. Thanks for helping!

Kind regards
