You can still add a sub process and use the scope of the sub process to set variables.

Best regards,

I am facing the same issue. I would like to see that from the UI, we can pass down task level variables just like we do for process to sub process.

Hi,

current implementation is the same


  public Map<String, Object> getTaskLocalVariables() {
    Map<String, Object> variables = new HashMap<String, Object>();
    if (queryVariables != null) {
      for (VariableInstanceEntity variableInstance: queryVariables) {
        if (variableInstance.getId() != null && variableInstance.getTaskId() != null) {
          variables.put(variableInstance.getName(), variableInstance.getValue());
        }
      }
    }
    return variables;
  }
  public Map<String, Object> getProcessVariables() {
    Map<String, Object> variables = new HashMap<String, Object>();
    if (queryVariables != null) {
      for (VariableInstanceEntity variableInstance: queryVariables) {
        if (variableInstance.getId() != null && variableInstance.getTaskId() == null) {
          variables.put(variableInstance.getName(), variableInstance.getValue());
        }
      }
    }
    return variables;
  }
