To decide between using Check App State and On Element Appear in UiPath, let’s analyze both functionalities based on their typical uses:
Check App State:
This is a modern activity designed to replace certain classic activities such as Element Exists
It allows you to check if an element is in a particular state (appears or does not appear) within a given timeout period.
If the element appears within the timeout duration, the workflow can proceed immediately. Otherwise, you can handle the absence of the element within the Target does not appear section.
Example Use Case:
Ensuring a login page’s element appears before filling in credentials. If the element appears, the automation proceeds to the login step; otherwise, it might handle an alternate action.
On Element Appear:
This classic activity pauses the workflow until a specified element appears on the UI.
Once the element appears, the remaining activities within this scope are executed.
This is useful for synchronizing the automation flow dynamically based on when UI elements become available.
Example Use Case:
Waiting for a notification element to appear after clicking a button to ensure the action succeeded.
Analysis Based on Usage
Check App State is more versatile and integrates well with modern automation needs, checking both the presence and absence of elements.
On Element Appear is specifically for ensuring synchronization by waiting for a specific element to become available before proceeding.
Recommendation:
If you need to wait for an element to appear and then run the next activity:
Use Check App State—it’s designed to be more robust and feature-rich, enabling better handling within modern automation workflows.
Check App State Features:
Check App State works the same way as Element Exists, has additional features, and is the modern activity that replaces Element Exists.
On Element Appear Limitations:
On Element Appear is a classic activity; by this point, you should be working in modern. The Check App State activity may function better for your needs.
