I have a Java application that uses a JTable to display some data. I want to enter the data from a JDialog.
The problem that I am facing is that the main window GUI won't refresh anymore after the JDialog opens. I have tried to change it to a JFrame and I get the same behavior. The same happens if I change the JTable with a JPanel. Everything works fine until a window opens on top of the main window. After this, the GUI elements won't refresh but the buttons will still react to clicks.
Could someone please help me understand what is wrong.
Sorry for not sharing any code. It was 5 in the morning and I totally forgot.
I have a frame with a JTable and a JButton. The button opens the JDialog. The JDialog has a panel nested with a JTextField and a JButton. When I press the button in the JDialog it sends the data to the main frame. There I want to populate the table with the data received. I can see the data in the debuger. The problem is that it won't show in the table until I restart the application. I also added a button in the same frame as the table to test the data insertion and it worked just fine.
