I am using Rapidclipse X (Vaadin 14, JPA/Hibernate) and a MySql database. By means of JPA/hibernate i store input data from a UI into the MySql database. That works fine so far. However when i want to display the data inside a grid, nothing happens, only a grey line appears.
this.grid.setDataProvider(DataProvider.ofCollection(TestDAO.INSTANCE.findAll()));
That's how I try to get the data.
The grid gets displayed in a dialog. How do i make the grid visible in the dialog?
