An example of delete object properties is represented in the image below:

delete object properties

There are two sets of properties for this activity, those in the dialog box on the left, and those in the properties pane on the right.

The delete object properties pane consists of the following sections:

3 Action Section

The Action section of the properties pane shows the action associated with this activity.

You can open a dialog box to configure this action by clicking the ellipsis () next to the action.

You can also open the dialog box by double-clicking the activity in the microflow or right-clicking the activity and selecting Properties.

3.1 Object or List

The name of the object or list of objects that will be deleted. If you choose a list, all objects in that list will be deleted.

3.2 Refresh in Client

This setting defines whether data sources are rerun after objects are deleted from the database.

Default: No

3.2.1 Microflow is Called from the Client in an Online App

If Refresh in client is set to No, the data sources are not rerun, and widgets which need to reload data will still display the object(s).

If set to Yes, the deletion is reflected across the client, which includes reloading the relevant data sources.

3.2.2 Microflow is Called in an Offline, Native, or Hybrid App

When inside a microflow that is called from an offline, native, or hybrid app, the Refresh in client option is ignored and functions as if it was set to No.

For more information, see the Microflows section of the Offline-First Reference Guide.

4 Common Section

For more information on properties in this section, see Common Properties.

5 What Happens During a Delete?

Clicking a Delete button or triggering a delete activity will initiate the delete events. In addition, when an object is removed through the configured delete behavior, it will execute all before and after events.

  • Events: all before and after events are executed, and if any before-delete event returns false, an exception can be thrown
    • If an exception occurs during an event, all the applied changes are reverted with the default error handling behavior
    • Changes made prior to the rollback will be kept
  • Database: if an object has the state Instantiated, there will be no database communication required
    • For any other status, a delete query is executed in the database
  • Result: the object will be removed from memory and if applicable from the database
    • All delete behavior for the associations is validated, and any associated objects are removed as well
