Hi, In my app, every time I enter a new record it is placed in automatic form at the end of the elements of a container. When I read the database I sort the records by date so that the most recent one appears first. I did not find any method that would allow me to order the elements and proceeded to create one assuming that the last included element should move to the first position. My problem is that I create a temporary container and every time I try to add a new element it sends me an error message that it already exists.
