SNOW-CAD User Interface Development Practice Question
A service portal widget is supposed to load data from a table and display it in a list. The widget renders but shows no data. Which 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
✓
An error in the widget's server script prevents data from being queried.
The widget renders (client-side works) but shows no data, indicating the server-side script that queries the table failed. Option A (ACL denial) would typically show an error or empty data but is less common than a script error. Option B (client script syntax error) would affect interactivity, not initial data load. Option C (portal page not configured) would prevent the widget from rendering entirely.
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 table's ACL denies read access to the user.
Why it's wrong here
ACL issues typically produce a different error or empty result, but it's less likely if other widgets show data.
- ✗
The widget's client script has a syntax error.
Why it's wrong here
Client script errors affect user interactions, not the initial data load.
- ✗
The portal page is not configured to include the widget.
Why it's wrong here
If the widget renders, it is included on the page.
- ✓
An error in the widget's server script prevents data from being queried.
Why this is correct
The server script is the primary data source; a scripting error would cause no data to be returned.
