Fails in eclipse 3.1M6 the same code that works fine in 3.1M5a.
I want to create a view (from other view) in the placeholder that is not the 
default placeholder.

Example:

I work with rcp.browser example.
I create a new view that shows a text (a parameter)

package org.eclipse.ui.examples.rcp.browser;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Label;
import org.eclipse.ui.part.ViewPart;

public class BlankView extends ViewPart {
  Label nameLabel;
  Composite mainPanel;

  public void createPartControl(Composite parent) {
    mainPanel = new Composite(parent, SWT.NONE);
    mainPanel.setLayout(new GridLayout());
    nameLabel = new Label(mainPanel, SWT.NONE);
  }

  public void setFocus() {
    //   nothing
  }

  public void setText(String text) {
    nameLabel.setText(text);
    mainPanel.layout(true);
  }
}

I create 2 place holder: The left to HistoryView & BlankView and the 
rigth to browser view. I want that history view is visible always.

Modify BrowserPerspectiveFactory.createInitialLayout as :

public void createInitialLayout(IPageLayout layout) {
  layout.addView(IBrowserConstants.BROWSER_VIEW_ID, IPageLayout.RIGHT, .25f, 
IPageLayout.ID_EDITOR_AREA);
  IFolderLayout left = layout.createFolder("left", IPageLayout.TOP, 0.3f, 
IPageLayout.ID_EDITOR_AREA);
  left.addPlaceholder(IBrowserConstants.BLANK_VIEW_ID);  // added constant 
to IBrowserConstants
  left.addView(IBrowserConstants.HISTORY_VIEW_ID);

  IViewLayout historyLayout = 
layout.getViewLayout(IBrowserConstants.HISTORY_VIEW_ID);
  historyLayout.setCloseable(true);
  layout.setEditorAreaVisible(false);
 }

and when HistoryView is created, open the BlankView. This is the 
HistoryView.createPartControl()
public void createPartControl(Composite parent) {
  viewer = new TreeViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL);
  drillDownAdapter = new DrillDownAdapter(viewer);
  viewer.setContentProvider(new ViewContentProvider());
  viewer.setLabelProvider(new ViewLabelProvider());
  viewer.setInput(getViewSite());
  makeActions();
  hookContextMenu();
  hookDoubleClickAction();

  // new code added
  try {
    BlankView view = (BlankView) 
getSite().getWorkbenchWindow().getActivePage().showView
(IBrowserConstants.BLANK_VIEW_ID);
    view.setText("Hello world");
  }
  catch (PartInitException exception) {
    exception.printStackTrace();
  }

 }

When HistoryView is created, open the blankView on the left place holder.
When i use eclipse 3.1M5a, works fine, but this same code, when use 3.1M6 
BlankView & HistoryView are gray views. When click more times on this views, 
show fine.

More: if comment this line 
left.addPlaceholder(IBrowserConstants.BLANK_VIEW_ID);  in 
BrowserPerspectiveFactory.createInitialLayout the views works fine on the 
rigth place holder.
