How to update property value from front end graph to server model

[wss29]

Hi
I want to know when I change the model property on the front graph, How could I update the value to the model? and by what kind of action or operation. like follow picture shows, I changed the name of a node, and I want to update the server model, I do not know how to implement this. I have thought to create a custom action, but is there any built-in method to do this?

HI @wss29 ,
Typically model property updates are highly domain specific and require some sort of customization anyways so we currently don't offer a generic mechanism for this.
So using a custom action is the recommended approach here. For your usecase, you should probably implement a custom updateOperation and implement the corresponding OperationHandler.
