Hi, found a working example at Sample Application with Subflow. I think it could be because your subflow execution is asynchronous, in which case the process continues without waiting for the results of the subflow.

Thanks Anders . That's what I found as well. I should have mentioned that switching it to Synchronous works fine. The problem is that I need an async subflow. Is there a way for an async subflow to interact with the workflow variables of the parent process? I guess I could do this with something like the [Multiple Approval](https://dev.joget.org/community/display/KBv6/Multiple+Approval) example, but I was hoping to be able to use the subflow framework. Thanks

As Anders mentioned, this doesn't work with Async subflows.  If anyone is interested, I was able to accomplish this with a combination of Async subflows and Bean Tools.  I have a Bean Tool in the parent flow that puts the parent ProcessId in a workflow variable:

import org.joget.workflow.model.service.*;
 
WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");
wm.activityVariable(workflowAssignment.getActivityId(),"wfProcessId", "#assignment.processId#");

The `wfProcessId` is passed into the subflow as an IN variable.  

Then I have a Bean Tool as the last step in the Async SubFlow that passes the workflow variables that were set in the subflow, back up to the parent flow.  

import org.joget.workflow.model.service.*;
import java.lang.Exception;
import org.joget.commons.util.LogUtil;

WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");

wm.processVariable("#variable.wfProcessId#", "wfParentFlowVariableName", "#variable.wfSubFlowVariableName#");

If there's an easier way to do this, please let me know. 

Thanks!
