[Olivier@xxxxxxxxxxxx]

Hi,

example, but when i choose my wizard and click on the next button, i get the
following exception :

The code of my wizard is :

package cetip.eclipse.plugin.nome;

import org.eclipse.jface.viewers.IStructuredSelection;
import org.eclipse.jface.wizard.Wizard;
import org.eclipse.jface.wizard.WizardDialog;
import org.eclipse.ui.INewWizard;
import org.eclipse.ui.IWorkbench;
import org.eclipse.ui.internal.Workbench;
import org.eclipse.ui.wizards.newresource.BasicNewFileResourceWizard;

/**
 * @author Olivier
 *
 */
public class NewMenuWizard extends Wizard{

	IWorkbench _workbench ;
	IStructuredSelection _selection;

	

	/**
	 * Constructor for NewMenuWizard.
	 */
	public NewMenuWizard() {
		super();
	}

	public void init(IWorkbench in_workbench , IStructuredSelection
in_selection ){
		_workbench = in_workbench;
		_selection = in_selection;
	}
	
	/**
	 * @see org.eclipse.jface.wizard.IWizard#performFinish()
	 */
	public boolean performFinish() {
		return false;
	}

	/**
	 * @see org.eclipse.jface.wizard.IWizard#addPages()
	 */
	public void addPages() {
		NewMenuPage nmp = new NewMenuPage( "Criação de Menu" ,
_selection );
		addPage( nmp );
	}
	
	public static void main(String[] args) {
		  // Create the wizard
      NewMenuWizard wizard = new NewMenuWizard();
      wizard.init(null, null);

      // Create the wizard dialog
      WizardDialog dialog = new WizardDialog
         (null,wizard);
      // Open the wizard dialog
      dialog.open();
		
	}

}

Olivier.
