    <p>I'm using italian locale for my program so <code>Float.parseFloat("8,00")</code> must function well. But I have encountered a very bad NFE in the following line:</p> <pre><code>this.cuSurfaceJTextField1.setValue( String.format("%05.2f",info.getCuSurface())); </code></pre> <p>I note that the above code used to work well up to some changes I made to the listeners that don't look to be related to this line of the code.(Now I have a propertyChangeListener that updates the model when the value is changed.</p> <pre><code>this.cuSurfaceJTextField1.addPropertyChangeListener("value", new PropertyChangeListener() { @Override public void propertyChange(PropertyChangeEvent evt) { info.setCuSurface(Float.parseFloat( (String)cuSurfaceJTextField1.getValue())); updateCuSurface(); } }); </code></pre> <p>The useful part of the exception:</p> <pre><code>Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "08,00" at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1241) at java.lang.Float.parseFloat(Float.java:452) at View.bars.QuadrateJPanel$11.propertyChange(QuadrateJPanel.java:348) at java.beans.PropertyChangeSupport.fire(PropertyChangeSupport.java:335) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:328) at java.beans.PropertyChangeSupport.firePropertyChange(PropertyChangeSupport.java:263) at java.awt.Component.firePropertyChange(Component.java:8382) at javax.swing.JFormattedTextField.setValue(JFormattedTextField.java:799) at javax.swing.JFormattedTextField.setValue(JFormattedTextField.java:502) </code></pre>

    2. CO@Simplefish That's right! Maybe that line of my code was never executed before and I thought that it works well! I tested it a simple sample. Isn't there something that gives me a localized parseFloat? the value that java returns me has , and it isn't a good practice to change it.

    3. CO@HotLicks I must convert and format the value because my JFormattedTextField is masked as "##,##". So I need String

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.
