CIS-ITSM Service Catalog And Request Management Practice Question
A Catalog Client Script of type 'OnChange' is written for a variable inside a Multi-Row Variable Set (MRVS). The script fails to execute when the user changes the variable value within the grid modal. What is the reason for this behavior?
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
✓
Multi-Row Variable Sets execute client-side logic inside an isolated modal scope where standard g_form methods for MRVS require specialized functions.
Standard Catalog Client Scripts do not support running OnChange events inside Multi-Row Variable Sets; specialized MRVS scripting or specific methods must be used.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Catalog Client Scripts cannot run on variables contained within variable sets.
Why it's wrong here
Standard variable sets support client scripts; multi-row variable sets have unique runtime limitations.
- ✓
Multi-Row Variable Sets execute client-side logic inside an isolated modal scope where standard g_form methods for MRVS require specialized functions.
Why this is correct
MRVS uses specific client script structures and does not support standard g_form OnChange scripts directly for grid rows in older implementations without specific design approaches.
- ✗
The script execution order is set to 100 instead of 0.
Why it's wrong here
Execution order controls sequence, not basic feature support.
- ✗
The client script UI type must be set to 'Desktop' only.
Why it's wrong here
UI type should typically be 'All' to ensure execution across platforms, but this is not the root cause of MRVS script failure.
