SNOW-CAD User Interface Development Practice Question
A reference field on a form shows a list of records, but the user cannot see any results when typing. The reference qualifier is set to 'active=true'. 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
✓
There are no records that satisfy the reference qualifier condition.
If the reference qualifier condition 'active=true' filters out all records (e.g., all records are inactive), no results appear. Option A is incorrect: lack of read access would prevent the user from seeing any records at all, but the user can see the field and type. Option C is incorrect: a read-only field prevents editing but does not affect searching for new records. Option D is incorrect: if no reference table were specified, the field would not function; the problem is the qualifier filtering.
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 user does not have read access to the referenced table.
Why it's wrong here
ACLs would block the entire field, not just the list.
- ✓
There are no records that satisfy the reference qualifier condition.
Why this is correct
A restrictive reference qualifier can result in an empty list.
- ✗
The field is read-only and prevents searching.
Why it's wrong here
Read-only fields can still show dropdowns but may appear disabled.
- ✗
The field's dictionary entry does not have a reference table specified.
Why it's wrong here
If the table were missing, the field would not work at all.
