    <p>I've made a GUI with <code>JFrame</code> which includes a <code>JComboBox</code> with several <code>JTextFields</code>. When I choose an item in the <code>JComboBox</code> the text fields changes their values and I am suppose to be able to change them. The thing is, when I've chosen an item and changes a value the combo box gets stuck with that certain item and I cant choose another from the combo box. (The drop down menu wont show how much I press it). Here's the GUI class and the <code>ActionListener</code> classes just calls a method in my GUI class. </p> <p>Can the problem be with I am using static methods and variables?</p> <pre><code>package GUI; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import java.awt.GridLayout; import java.awt.Panel; import java.awt.Toolkit; import java.util.HashMap; import javax.swing.JButton; import javax.swing.JComboBox; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextField; import GUIListeners.CloseListener; import GUIListeners.RoleBoxListener; import GUIListeners.SaveEditListener; import Simulation.Project; public class EditProjectGUI extends JFrame { private static Project project; private JLabel editLabel, selectRole, savedLabel; private static JComboBox roleBox; private JLabel preConceptLabel, conceptLabel, projectLabel, preRampLabel, rampLabel, highVolumeLabel, preEOLLabel, EOLLabel; private static JTextField preConceptText, conceptText, projectText, preRampText, rampText, highVolumeText, preEOLText, EOLText; private JButton saveButton, cancelButton; public EditProjectGUI(Project project) { this.editLabel = new JLabel("Edit Projects Details"); editLabel.setFont(new Font("sansserif", Font.BOLD, 20)); editLabel.setForeground(new Color(83, 142, 213)); selectRole = new JLabel("Select role: "); this.project = project; saveButton = new JButton("Save"); saveButton.addActionListener(new SaveEditListener()); cancelButton = new JButton("Cancel"); cancelButton.addActionListener(new CloseListener(this)); savedLabel = new JLabel("Not saved"); savedLabel.setForeground(new Color(192, 80, 77)); setTitle("Edit Projects Data"); int xSize = 400; int ySize = 300; setSize(xSize, ySize); setVisible(true); Toolkit kit = Toolkit.getDefaultToolkit(); Dimension currentScreen = kit.getScreenSize(); this.setBounds(currentScreen.width / 2 - xSize / 2, currentScreen.height / 2 - ySize / 2, xSize, ySize); setLayout(new BorderLayout()); add(editLabel, "North"); String[] roles = { "OPM", "MM", "SE", "QM", "SCP" }; roleBox = new JComboBox(roles); roleBox.addActionListener(new RoleBoxListener(this)); Panel centerPanel = new Panel(); centerPanel.setLayout(new GridLayout(9, 2)); preConceptLabel = new JLabel("Pre-Concept: "); conceptLabel = new JLabel("Concept: "); projectLabel = new JLabel("Project: "); preRampLabel = new JLabel("Pre-Ramp: "); rampLabel = new JLabel("Ramp: "); highVolumeLabel = new JLabel("High Volume: "); preEOLLabel = new JLabel("Pre-EoL: "); EOLLabel = new JLabel("EoL: "); preConceptText = new JTextField(); conceptText = new JTextField(); projectText = new JTextField(); preRampText = new JTextField(); rampText = new JTextField(); highVolumeText = new JTextField(); preEOLText = new JTextField(); EOLText = new JTextField(); centerPanel.add(selectRole); centerPanel.add(roleBox); centerPanel.add(preConceptLabel); centerPanel.add(preConceptText); centerPanel.add(conceptLabel); centerPanel.add(conceptText); centerPanel.add(projectLabel); centerPanel.add(projectText); centerPanel.add(preRampLabel); centerPanel.add(preRampText); centerPanel.add(rampLabel); centerPanel.add(rampText); centerPanel.add(highVolumeLabel); centerPanel.add(highVolumeText); centerPanel.add(preEOLLabel); centerPanel.add(preEOLText); centerPanel.add(EOLLabel); centerPanel.add(EOLText); add(centerPanel, "Center"); Panel southPanel = new Panel(); southPanel.setLayout(new FlowLayout()); southPanel.add(saveButton); southPanel.add(cancelButton); southPanel.add(savedLabel); add(southPanel, "South"); updateTextField(this); } public static void updateTextField(JFrame frame) { String role = (String) roleBox.getSelectedItem(); HashMap&lt;String, Double&gt; map = project.getMap(role); preConceptText.setText(map.get("Pre-Concept").toString()); conceptText.setText(map.get("Concept").toString()); projectText.setText(map.get("Project").toString()); preRampText.setText(map.get("Pre-Ramp").toString()); rampText.setText(map.get("Ramp").toString()); highVolumeText.setText(map.get("High Volume").toString()); preEOLText.setText(map.get("Pre-EoL").toString()); EOLText.setText(map.get("EoL").toString()); frame.validate(); } public static void save() { String role = (String) roleBox.getSelectedItem(); HashMap&lt;String, Double&gt; map = new HashMap&lt;String, Double&gt;(); map.put("Pre-Concept", new Double(preConceptText.getText())); map.put("Concept", new Double(conceptText.getText())); map.put("Project", new Double(projectText.getText())); map.put("Pre-Ramp", new Double(preRampText.getText())); map.put("Ramp", new Double(rampText.getText())); map.put("High Volume", new Double(highVolumeText.getText())); map.put("Pre-EoL", new Double(preEOLText.getText())); map.put("EoL", new Double(EOLText.getText())); project.setMap(map, role); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
