Hello,
I've faced an exception, the one stated in topic.
I've been working on same code for a week. I've updated the code outside the activity related things but as a result I'm having this problem.

The code is like that:

public Data getDataFromExecutionId(String executionId) {
   ExecutionEntity executionEntity = (ExecutionEntity) getRuntimeService().createExecutionQuery().executionId(executionId).singleResult(); //this returns a process instance

   if (executionEntity == null) {
      return null;
   }
   String orderDataPlaceholderName = getPropertySourcesPlaceHolderConfigurer().resolvePlaceholder(VariableNameConstants.ORDER_DATA_EXP_NAME);
   Data data = (Data) executionEntity.getVariable(orderDataPlaceholderName); //this line throws "lazy loading outside command context"
}

org.activiti.engine.ActivitiException: lazy loading outside command context
   at org.activiti.engine.impl.persistence.entity.VariableScopeImpl.ensureVariableInstancesInitialized(VariableScopeImpl.java:58)
   at org.activiti.engine.impl.persistence.entity.VariableScopeImpl.getVariable(VariableScopeImpl.java:84)
   at …SimpleProcessManager.getDataFromExecutionId(SimpleProcessManager.java:77)
‍‍‍‍‍‍

What can be the cause of this?

Thanks…

You should use the Activiti Service API to access the variable data or setup a command context yourself. So the easiest approach would be to get the variable data through the RuntimeService API.
