Refreshing transient field in editor

I created Order and OrderLine entities, and added a transient field to calculate the total of all line amount. The order total transient field is in the Order edit screen and it only get refreshed when the Order is saved.

How i can refresh the order total amount without exiting and entering the Order edit screen again to display the updated total amount of all the line items?

I’m not sure what you mean. Could you provide a sample project?

Hi Konstantin,

Never mind. I think transient field is not suitable in my specific situation. I have use another method to solve my issue. Thanks anyway.
