How to reference a variable under the same catalog item from a variable set (Reference qualifier).

[k-tsumori]

Hello All,I have the following setup, but Variable 2 isn’t working as intended. I’d like advice on how to fix or improve it.

Configuration:

• Variable 1 (directly under the Catalog Item)

  • Name: va_category
  • Type: Reference
  • Type specifications:
    • Reference: sys_choice
    • Use reference qualifier: Advanced
  • Reference qualifier:
    javascript:"element=category^name=incident^inactive=false^language="+gs.getUser().getLanguage();

• Variable set: vs_subcategory_details

• Variable 2 (inside the variable set)

  • Name: va_subcategory
  • Type: Reference
  • Type specifications:
    • Reference: sys_choice
    • Use reference qualifier: Advanced
  • Reference qualifier (not working):
    javascript:"name=incident^element=subcategory^inactive=false^dependent_value="+current.variables.va_category.value+"^language="+gs.getUser().getLanguage()

I want Variable 2 to show only the subcategories for the category selected in Variable 1.
This works if both variables are directly under the catalog item, but it fails when Variable 2 is inside a variable set.

If this is achievable, could you please advise on the correct approach or best practice?

@Ankur Bawiskar ,I was able to confirm that the sysid of variable 1 is displayed in hiddenVariableName.

However, variable 2 did not work.
I suspect variable 2 may not function properly unless the value of sys_choice is passed to it. What do you think?

@k-tsumori 

correct, that's the reason.

we are storing sysId but the ref qualifier requires the value of that choice

you can do this in your onLoad catalog client script

function onLoad() {

    var cat = g_service_catalog.parent.getValue("va_category");

   // use GlideAjax here and pass the sysId and query sys_choice with that sysId and return value and then set in hidden field

    g_form.setValue('hiddenVariableName', cat);
    g_form.setDisplay('hiddenVariableName', false);

}

@Ankur Bawiskar ,How should I specifically write the script for the following?

// use GlideAjax here and pass the sysId and query sys_choice with that sysId and return value and then set in hidden field

I hope you are aware how GlideAjax script is written.

if not then check this and enhance

@Ankur Bawiskar ,

Thanks to your help, I was able to resolve the issue.
Using the following client script, I achieved the desired behavior.
(I’m omitting the Script Include here.)

function onLoad() {

    var cat = g_service_catalog.parent.getValue("va_category");

    if (!cat) {

        g_form.setDisplay('hiddenVariableName', false);

        return;

    }

    var ga = new GlideAjax('script_Include_name');

    ga.addParam('sysparm_name', 'getChoiceValue');

    ga.addParam('sysparm_sys_id', cat);

    ga.getXMLAnswer(function(response) {

        g_form.setValue('hiddenVariableName', response);

        g_form.setDisplay('hiddenVariableName', false);

    });

}
