Hey @harshal001
try this :
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || oldValue === newValue)
return;
var field = 'u_fault_category';
// Reset field
g_form.setValue(field, '');
g_form.clearOptions(field);
g_form.addOption(field, '', '-- None --', 0);
if (!newValue)
return;
var selectedCategory = newValue;
var ga = new GlideAjax('NCS_FaultCategoryAjax');
ga.addParam('sysparm_name', 'getFaultCategoriesByOpsCategory');
ga.addParam('sysparm_ops_category', selectedCategory);
ga.getXMLAnswer(function(answer) {
// Ignore stale Ajax responses
if (g_form.getValue('u_operations_category') != selectedCategory)
return;
if (!answer)
return;
var choices = JSON.parse(answer);
g_form.clearOptions(field);
g_form.addOption(field, '', '-- None --', 0);
choices.forEach(function(choice) {
g_form.addOption(field, choice.value, choice.label);
});
});

what is happening here when i select any First choice in Operations category then fault choice displayed as mapping done, but when switch the choice for operation category then in fault category choices are not displayed without reloading the page.... This issue I am getting now.
Even I have try with dictionary table configuration Depend on field Checkbox checked
This way Fault, Service Request, Inquiry is mapping directly using dictionary choice dependent field. but for adhoc only i am getting this issue

Hey @harshal001
From your description, it looks like the Script Include is working correctly because the Fault Category choices are populated the first time you select an Operations Category. The problem occurs only when switching to another Operations Category without reloading the form.
A few questions and observations:
- Is u_fault_category a Choice field or a Reference field?
- Are you testing this in Classic UI, Service Portal, or Workspace?
You mentioned that enabling the Dependent field in the Dictionary works correctly for Fault, Service Request, and Inquiry, but not for Adhoc. That suggests the issue is likely related to the field configuration or choice records rather than the GlideAjax call itself.
Please verify the following:
- Dependent Choice Configuration
Check whether the Adhoc choices exist in the sys_choice table with the correct Dependent Value.
If Adhoc does not have matching dependent choice records, the field will appear blank after the parent value changes.
2. Client Script
Before repopulating the choices, reset the field value and clear the existing options:
g_form.setValue('u_fault_category', '');
g_form.clearOptions('u_fault_category');
g_form.addOption('u_fault_category', '', '-- None --', 0);
3. GlideAjax Response
Add a console.log(response); inside the callback to confirm that the Script Include is returning the expected JSON when Adhoc is selected.
4. Conflicting Logic
Check for any other Client Scripts, UI Policies, or Dictionary dependencies that may be clearing or filtering the choices after your callback executes.
Since the issue occurs only for Adhoc, my first suspicion would be that the dependent choice configuration or the mapping for Adhoc is incomplete or conflicting with the dynamically added options.
Could you also share:
- The choice records for Operations Category = Adhoc.
- Whether u_fault_category is using both Dictionary dependent choices and GlideAjax at the same time?
Using both approaches together can sometimes result in the dynamically added options being removed by the platform's built-in dependent choice filtering.
