A business rule updates a field on the incident table after submission. However, the updated value is not displayed on the form when the record is opened again. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A client script (onLoad) is setting the field back to its original value.
A client script (onLoad) can run after the record is opened and set the field back to its original value, overriding the value updated by the business rule. Option A is incorrect because the form does refresh when the record is opened, so the issue is not a lack of refresh. Option B is incorrect: asynchronous business rules still save their updates to the database; the timing of execution does not affect whether the value persists on the form. Option D is incorrect because hiding a field via UI Policy does not change its value; the value would still be stored.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The form is not refreshing after submission.
Why it's wrong here
The form automatically refreshes when the record is opened again.
- ✗
The business rule is set to run asynchronously.
Why it's wrong here
Asynchronous rules still update the record; the value should persist.
- ✓
A client script (onLoad) is setting the field back to its original value.
Why this is correct
Client scripts execute after the form loads and can override server-set values.
- ✗
A UI Policy is hiding the field.
Why it's wrong here
Hidden fields still contain values; they just aren't visible.
