Since your Sector_Activity in nested within Customer Cdt, and your choice values are integer id's, you should update you value and saveinto to append .id, like:

ri!customer.Sector_Activity.id

assuming, id is the field in Sector_Activity where you wanna store your selection value

i solved the problem , now it is working

i had to do cast my result from the query entity (because it s returning a dictionary of CDT ) as you say , so i did a casting to a list of my CDT.

like in the picture , now i can display the content and save it in the rule input.

This is a tricky issue to troubleshoot - I believe what's happening is that there is a type mismatch between your choiceValues and your saved value. The choiceValues are of type dictionary (because that is what is returned by a!queryEntity()), but the value is of type Sector_Activity. For a dropdown field to work, the types and values must exactly match.

It actually looks to met that you're pretty close with yoru commented out code - if you run the cast you already have there against your query result, it should cast correctly and it should eliminate the type mismatch.

The value AND data type of the parameters value and choicevalues must match. I assume that you want to store the ID of the selected sector and customer.Sector_Activity is an integer. Then

choiceValues: local!query_data_activity_sector.ID

should work.

BTW, your variable naming seems to not match the Appian best practices,
