getDisplayValue() Returns Blank in Catalog Client Script When Adding Select Box Choices

[gdo]

Hi everyone,

I am trying to dynamically add choices to a Select Box in a Service Catalog item based on the selected Entity. The logic is:

• If the Entity contains "abc", add two new MacBook choices.
• I can get the sys_id of the selected Entity using newValue, but when I try getDisplayValue(), it returns blank.

Issues & Questions:

1. Why is getDisplayValue('entity') returning blank?
2. Since I only have the sys_id, what’s the best way to get the display value inside a Catalog Client Script?
3. Is there a better approach to dynamically add choices when "abc" is in the Entity name?

Is entity variable a reference variable?

If yes then the way how display value works is different in portal and native

here is my blog which talks about the same.

Hello,

Yes it is a reference, to the core_company table.
I saw your blog, but when I use :

var v = g_form_getDisplayValue("entity");

alert(v)

>> The alert on the portal returns blank. 
I tried every method existing to get the display value. I only get the sys_id with newValue variable

@gdo There is an issue with your code. Use the following.

var v = g_form.getDisplayValue("entity");
alert(v);

Hello @gdo 

Please use g_form.DisplayBox('reference field name').value;

Please mark this as helpful / accepted solution if it resolves your issue.
