Build Identifier: M20110210-1200 Eclipse 3.6.2

I utilize the org.eclipse.ui.internal.wizards.datatransfer.WizardArchiveFileResourceImportPage1 class to import a zip file in my custom made IDE. This Page is put in an import wizard, but it is preceded by a project creation page that creates the project before this wizard page page is displayed (all in the same wizard). With this new structured selection (the new project), I would like to reinitialize my WizardArchiveFileResourceImportPage1 so that the "Into folder" selection appears updated with the newly created project. 

Extending the WizardArchiveFileResourceImportPage class (extends WizardFileSystemResourceImportPage1 which in turns extendsWizardResourceImportPage) in my own page does not achieve anything as the "Into folder" value is embedded in the super class WizardResourceImportPage so i cannot reinitialize it programmatically. 

I propose to add an "init" function to WizardResourceImportPage that will do the following and will be accessible by the subclasses in the hierarchy structure: 

    protected void reinitializeCurrentResourceSelection(IStructuredSelection selection) {
        //Initialize to null
        currentResourceSelection = null;
        if (selection.size() == 1)
        {
            Object firstElement = selection.getFirstElement();
            if (firstElement instanceof IAdaptable)
            {
                Object resource = ((IAdaptable) firstElement).getAdapter(IResource.class);
                if (resource != null)
                {
                    currentResourceSelection = (IResource) resource;
                }
            }
        }

        if (currentResourceSelection != null)
        {
            if (currentResourceSelection.getType() == IResource.FILE)
            {
                currentResourceSelection = currentResourceSelection.getParent();
            }

            if (!currentResourceSelection.isAccessible())
            {
                currentResourceSelection = null;
            }
        }
        containerNameField.setText(currentResourceSelection.getFullPath().makeRelative().toString());
    }
