ActivitiException - couldn't find type for

[opal]

Hi,

When starting the process using REST I send the following json string with the query:

{
   "processDefinitionId":"movieOrder:1",
   "movie":{
      "id":"7",
      "title":"A HARD DAYS NIGHT",
      "spiCode":"SPI3146",
      "movieVersions":[{
         "versionTitle":"LOL WERSJA",
         "timecode":"12:!2:12",
         "mediaId":"LOL ME",
         "distributor":"LOL DYST",
         "age":"12",
         "programType":"LOL TYP",
         "bw":"true",
         "description":"lol uw",
         "additional":"lol dod",
         "mnes":[{"id":"-1","mneFormat":"2.0 M\u0026E","broadcast":"true","description":"wefwef","tracks":[]}],
         "audios":[{"id":"-1","audioFormat":"2.0 MIX","codec":"QWD","lang":"QWD","description":"qwd","broadcast":"true","tracks":[]}],
         "videos":[{"id":"-1","broadcast":"true","fileFormat":"HD","fps":"25p","aspectRatio":"HDV 144","resolution":"HDV 144","lang":"QWD","description":"qwd","tracks":[]}]
      }]
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The server responses iwth the following message:

"status" :
  {
    "code" : 500,
    "name" : "Internal Error",
    "description" : "An error inside the HTTP server which prevented it from fulfilling the request."

What might be the reason of this exception? I've sent only primitives in the json msg.

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!
