In the loic for the second reference selector make sure the call is not performed when the input for the first reference selector is empty, then you do not have the issue that the list is automatically retrieved when opening the page.
Then on the select of the first reference selector add on on change activity that refreshes the entity to trigger the function that retrieves the data in the second reference selector and as the first selector is now not empty the call is performed.
This will also trigger the first selector datasource so you might need some logic in that retrieve to prevent this from happening.
Thanks for answer!
I have tried to achieve what you said but not really made it work.
This is my second reference selector’s microflow datasource (which will be empty while first entering the page).
The selectable objects from the second reference selector however won’t refresh after a change from the first reference selector, only the datasource microflow.
This is where I might go wrong.
How can I also update the list of selectable objects to my second reference selector and not only the datasoure microflow?
