Hi @Suggy ,
There are many example of synchronous GlideAjax
1. A user selects a category, and you need to fetch a list of subcategories immediately to populate another field dynamically.
2. Prevent submission of a catalog request if a similar request is already open.
3. A user selects a group, and the script checks if the user belongs to that group before showing specific UI components.
