If you are utilizing the UCI interface there is a new JavaScript handler available for the Business Process Flows (BPF), onPreStageChange . Unlike the onStageChange handler on Pre StageChange fires before the actual business process has been changed so that you can evaluate if you want the change to occur and prevent it if needed. With this new handler we can now get rid of many of the Synchronous workflows used previously to evaluate the changes made to a BPF. By removing these workflows the overall performance of your BPF changes should be increased. Additionally calling JavaScript code being before the change also eliminates additional problems such as the users clicking the Next/Previous multiple times before the workflows have been fired ( Tip #360 ) To utilize the new handler you will needed to create a function and then pass that function into the addOnPreStageChange function provided under executionContext.getFormContext().data.process. It is best practice to pass
