Inverse side of a ManyToMany realation is not automatically updated when adding an object to the owning side












0















I implemented a bidirectional ManyToMany relationship between two tables following the documentation.



I then wanted to unit-test the situation when I added an entry to the owning side relation. But then my query from the inverse side always ignored the new element.



I then realized that the correct values are only returned when I cleared the ObjectManager and freshly read all objects from the database. Once I saw this, I tried to manually update also the inverse side when adding the new object (as proposed when updating the inverse side) and then everything worked.



I now am looking for the location in the documentation where this is discussed to make shure that I do everything the correct way, but I can not find it. Maybe someone out here has a hint?

I tried all solutions from that topic with/without GlobalKey for Scaffold and Form but the problem wasn't fixed. I tried to build a authentication form with login and signup. But the keyboard doesn't show when I tap the TextFormField at the first time. Then I try to input some letter from physical keyboard, the widget is rebuilt.

But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
