invocationTargetException et ouverture de Shell
Bonjour la liste,
J'éxécute une mini application RCP. J'utilise un objet Wizard (org.eclipse.jface.wizard.Wizard).
Le code de ma classe Wizard est le suivant

public void addPages() {
addPage(new FrontPage());
addPage(new CustomerInfoPage());
addPage(new PaymentInfoPage());
}
public boolean performFinish() {
...
try {
// puts the data into a database ...
getContainer().run(true, true, new IRunnableWithProgress() {
public void run(IProgressMonitor monitor)
throws InvocationTargetException, InterruptedException {
monitor.beginTask("Store data", 100);
monitor.worked(40);
// store data here ...
System.out.println(data);
WidgetTest test = new WidgetTest();
Shell shell = test.getShell();
shell.open();
Thread.sleep(2000);
monitor.done();
}
});
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}catch (Exception e) {
e.printStackTrace();
}
//Display.getCurrent().dispose();
return true;
}
/* (non-Javadoc)

*/
public boolean performCancel() {
...
}

Une fois cliqué sur le bouton Finish, j'ouvre un shell. Le code de ce shell est le suivant

Shell topLevelShell = null;
public WidgetTest(){
topLevelShell = new Shell();
topLevelShell.setText("TopLevel.LigneTitre");
topLevelShell.setLayout(new GridLayout());
Button btnOpen = new Button(topLevelShell,SWT.PUSH);
btnOpen.setText("Ouvrir");
btnOpen.addSelectionListener(new SelectionListener(){
@Override
public void widgetDefaultSelected(SelectionEvent e) {
// TODO Auto-generated method stub
}
@Override
public void widgetSelected(SelectionEvent e) {
// TODO Auto-generated method stub
System.out.println("Bienvenue à Libreville");
}
});
}
public Shell getShell(){
return topLevelShell;
}

Mais seulement lors de l'exécution, quand je clique sur "Finish", j'ai l'erreur
