Similar exception is thrown when first clicking the drop-down arrow of the 'Generator name' list of 'Primary key generation' in the JPA Details view, and then choosing another mapping in the JPA Structure view. A fragment of the exception is as the following: java.lang.NullPointerException at org.eclipse.jpt.ui.internal.details.GeneratedValueComposite$3.setValue_(GeneratedValueComposite.java:158) at org.eclipse.jpt.ui.internal.details.GeneratedValueComposite$3.setValue(GeneratedValueComposite.java:147) at org.eclipse.jpt.ui.internal.details.GeneratedValueComposite$3.setValue(GeneratedValueComposite.java:1) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter.selectionChanged(AbstractComboModelAdapter.java:499) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter.comboSelectionChanged(AbstractComboModelAdapter.java:491) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter$3.modifyText(AbstractComboModelAdapter.java:223) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:173) Moving JPA specific bugs to new JPA component in bugzilla. |
Create the following Entity with the JPA Details view open. Select the @TableGenerator annotation and choose the Quick Fix 'Add missing attributes'. You'll get an NPE. No real side effect to this, just a logged NPE, if you type in a name the table generator name text field updates without problems. @Entity public class Employee { @Id @TableGenerator @SequenceGenerator private int id; } Caused by: java.lang.NullPointerException at org.eclipse.jpt.ui.internal.details.GeneratedValueComposite$3.setValue(GeneratedValueComposite.java:150) at org.eclipse.jpt.ui.internal.details.GeneratedValueComposite$3.setValue(GeneratedValueComposite.java:1) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter.selectionChanged(AbstractComboModelAdapter.java:499) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter.comboSelectionChanged(AbstractComboModelAdapter.java:491) at org.eclipse.jpt.ui.internal.swt.AbstractComboModelAdapter$3.modifyText(AbstractComboModelAdapter.java:223)
