Hi,

Activiti can store a virtually everything as a variable (long, string, double, short, date, JPAEntity, …) and also all java classes implementing Serializable.

Looks like you're starting the process with a process-variable which is a JSONObject, composed of other JSONObject/arrays. This is not serializable and cannot be used (out of the box).

What you can do is add a custom VariableType to the ProcessEngineConfiguration (right before the SerializableType) which can read/write JSON-object from a bytearray stored in the activiti tables. A good starting point for implementing this is to look at org.activiti.engine.impl.variable.SerializableType. Also have a look to org.activiti.engine.impl.variable.JPAEntityVariableType and see where it is used.

Ok, not it seems clear to me. I've resolved the problem in another way - assigned the json value to a string field and then I a process created a special task that parsed and stored the obtained object in the context. Thanks!
