Serializing Siena Models fails

Open simplysoft opened this issue 12 years ago • 2 comments

Model$ProxyMany seems not to be serializable, thus serializing of a siena model fails

play.exceptions.CacheException: Cannot cache a non-serializable value of type <model>

do you use Many<T> in GAE?

No, I use just the model entity type as the field type. An yes, its on GAE. I do have a model Organization and then several several other models that have an organization field. Trying to serialize one such model results in the given error message
