While working on some customers’ applications, I ran into a few performance and functionality tips related to list of values in Visual Builder Cloud Service (VBCS). While it is very tempting to use the built in quick start that binds a list to results from a service, in some cases you might want to take a different approach.
One reason is performance – some lists don’t change very often – and it makes more sense to fetch them only once instead of at every entry into a page. VBCS offers additional scopes for variables – and in the demo below I show how to use an application scope to only fetch a list of countries once (starting at 1:15). I also show how to define an array that will store the values of the list in a way that will allow you to access them from other locations in your app, and not just the specific UI component.
The other scenario that the demo shows relates to situations where you need to get additional information on the record you selected in the list. For example, your list might have the code and label but might contain additional meaningful fields. What if you need access to those values for the selected record? Read the complete article here.
