SWT 无法建立新的view

Question

这段时间我在做一个用到SWT的项目，第一次接触. 我想建立一个table view,table中的数据已经在数据库中建立了, model层也做好了. 不过我在建立UI层中出现了问题, 我有以下的一个异常 org.eclipse.ui.PartInitException: Could not create view. And I tag the code below:在 detail composit, 我建立了一个openTISComponent()，代码如下。/**
 * Action call - Opens TIS.
 * Function to change....
 * @param unitUnderTest
 *            UnitUnderTest
 */
private void openTISComponent() {
    final Tis tis = new Tis(); 
    final BigDecimal selectedEdrId = tis.getId();    final IWorkbench wb = PlatformUI.getWorkbench();
    final IWorkbenchWindow window = wb.getActiveWorkbenchWindow();    new TISTableViewPart(true, selectedEdrId, tis);
    try {
        window.getActivePage().showView(TISTableViewPart.ID);
    } catch (final PartInitException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }  
    }
然后在TISTableViewPart, 我写了一些方法去建立一个新的view:public class TISTableViewPart
    extends AbstractTableViewPart implements IContribution {public static final String ID =
        "de.conti.ip3.edr.main.gui.views.table.TISTableViewPart";
public static final DecimalFormat DF = new DecimalFormat("000000");
public static String versionName;
public static BigDecimal selectedEDRId;
private String objectUniqueIdentifier;
public static Tis tisComponent;
public static JEdrTIS tisEdr;public TISTableViewPart() {}/**
 * Constructor, taking as parameter.
 * @param template1
 *            boolean
 * @param selectedEdrId
 *            BigDecimal
 */
public TISTableViewPart(final boolean template1,
        final BigDecimal selectedEdrId,
        final Tis tis) {
    selectedObjectId = selectedEdrId;
    selectedEDRId = selectedEdrId; 
}@Override
public void addHelpToTableViewerPart() {
    // TODO Auto-generated method stub}/**
 * Instantiation of local composite.
 * @param parent
 *            Composite
 */
@Override
protected final void instantiateLocalComposite(final Composite parent) {    localComposite = new ComponentTableCompositeForTis(parent,SWT.NONE,true);}/**
 * Contribution class.
 * @param activePage
 *            IWorkbenchPage
 */
@Override
public final void contribute(final IWorkbenchPage activePage) {
    try {        activePage.showView(TISTableViewPart.ID);        activePage.setEditorAreaVisible(false);    } catch (final PartInitException ep) {
        ep.printStackTrace();
        MessageDialog.openError(activePage.getWorkbenchWindow().getShell(),
                "Error", "Error opening TIS view");
    }}
