SNOW-CSA UI, Navigation and Forms Practice Question
During form submission, a mandatory field is not highlighted in red, and the form submits without requiring it. The field is made mandatory by a UI Policy that checks a condition set by a Client Script on form load. What is the most likely issue?
⚠ Common exam trap
A common mix-up: candidates assume UI Policies and Client Scripts run in the order they appear in the application navigator, but ServiceNow explicitly evaluates UI Policy conditions before Client Scripts, regardless of the order they are created.

Correct answer & explanation
✓
The UI Policy runs before the Client Script
The UI Policy runs before the Client Script, so when the UI Policy evaluates its condition to determine whether to make the field mandatory, the Client Script has not yet set the condition variable. As a result, the UI Policy condition fails, the mandatory attribute is not applied, and the form submits without requiring the field. The correct order of execution is UI Policy conditions first, then Client Scripts, then UI Policy actions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A Data Policy overrides the mandatory attribute
Why it's wrong here
Data Policies enforce server-side and do not affect client-side highlighting.
- ✗
The UI Policy is set to OnSubmit
Why it's wrong here
OnSubmit would validate on submit, but the symptom is lack of client-side highlighting.
- ✗
The UI Policy runs after the Client Script
Why it's wrong here
If it runs after, the value would be set and the condition would apply correctly.
- ✓
The UI Policy runs before the Client Script
Why this is correct
UI Policies execute earlier in the form load sequence; if the condition depends on a client script value, it may be missed.
