Hello, I am completely new to Mendix and I am doing the Rapid Developer course right now. I followed everything how it should but when I go to run my program it will not let me because of error CE6897: Parameter "Course" is a persistable entity with an offlline synchronization which is not allowed in microflow called from a nanoflow... How can I go about fixing this? I looked at the documentation and it told me to do this: If you need to execute a microflow with a persistable object as parameter, you can define a before/after commit event handler on the desired persistable entity. When you create and commit an instance of this entity in the client and perform synchronization, the configured event handler (or handlers) will run. But I cannot understand how to accomplish this because I am a beginner. Please advise. Thank you, Sharni
