Both /runtime/tasks && /form/form-data?taskId=1000 responds with 'formKey': null (6.0.0.Beta2-SNAPSHOT)

I see someone else had this issue https://forums.activiti.org/content/access-activitiformkey-using-activiti-rest-version-513I've had a look at the mappings and handlers and traced them to database layer. The problem seems to be the formKey is not persisted to ACT_RU_TASK, in fact quite a few fields

The TaskEntityImpl in MybatisTaskDataManager(AbstractDataManager<EntityImpl>).insert(EntityImpl) line: 78 seems to contain the same missing values including formKey as are missing from the database ACT_RU_TASK

I'm trying to find where the parameters are assembled for the task insert … but it's difficult to trace execution through a command pattern arch.
org.activiti.engine.impl.agenda.ContinueProcessOperation - Executing activityBehavior class org.activiti.engine.impl.bpmn.behavior.UserTaskActivityBehavior

seems to trigger org.activiti.engine.impl.persistence.entity.TaskEntityImpl.insertTask through an event I'm guessing … but I can't seem to find the calling code and therefore where the parameters are assembled for the task insert … ?

Ok it looks like this is a bug in activiti-app, this problem doesn't seem to occur in a test case loading a resource direct from an bmpn20.xml file, because the formKey is there in the UserTask flowElement in the list in Process object. But in activity-app the the bmpn20.xml persisted as a blob to ACT_GE_BYTEARRAY omits the formKey. Inside it seems to be there earlier as in the json-converter seems to work and the bpmn-converter, it must get dropped before it's persisted to ACT_GE_BYTEARRAY

The bug can be found in com.activiti.service.runtime.DeploymentServiceImpl.retrieveFinalFormKey(String, FlowElement, Map<Long, Form>, AbstractModel, Long, Long, User)
