Invoke Entity

The Invoke Entity task is designed to refresh specific components, forms, or elements within an application page. You can also configure it to refresh the entire page, ensuring that all included elements are reloaded and updated.

Common Uses

1. Refreshing Updated Data:
   • When changes occur in the back-end database, this task ensures that the latest data is displayed on the page.
   • Example: In a banking app, after submitting a fund transfer, the transaction list can be refreshed to show the updated balance and new transaction entry.
2. Dynamic UI Updates:
   • Used for refreshing forms or components to reflect changes made by other actions in real-time.
   • Example: Refreshing a loan application form to show new fields or values based on the selected loan type.

This task is essential for maintaining data consistency and ensuring dynamic, user-friendly interactions within the application.

Configuration

When you create a task, its configuration page opens in which you define its basic and advanced properties. These are as follows:

Basic

Basic Properties	Description
Task Type	The Task Type indicates what kind of task you are creating. This is a read-only field since you select the type when you create the task and cannot change it during the configuration stage.
Reference Name	The Reference Name acts as a unique internal identifier for the task. This is visible to vFlow users for ease of reference but is hidden from end users. This allows users of the platform to manage and differentiate between tasks conveniently.
Name	The name defined here will be displayed to the end user.
Description	The Description field is intended for use by application designers or administrators (vFlow users) to provide additional context or details about the task group. This description is not visible to end-users and is used solely for internal reference to assist with task management.
