This event occurs before the status of a process instance changes.
Use the formContext.data.process.addOnPreProcessStatusChange method to add event handlers for this event and the formContext.data.process.removeOnPreProcessStatusChange method to remove them.
From within a web resource script registered to the onPreProcessStatusChange event, a developer can invoke the following on the executionContext object passed into the web resource script:
executionContext.getEventArgs().preventDefault();
When you invoke preventDefault:
- The state change will not be processed. The process instance will remain on the original stage in the original state.
- The save of the main form will not be processed. If the main form was in a dirty state, it would remain in a dirty state.
- Any web resources that registered onProcessStatusChange will not be invoked.
This client API is only supported on the unified client. The legacy web client does not support this client API.
