Bug 188570

Description Thony Lundin 2007-05-23 03:01:53 EDT

Build ID:  I20070503-1400

Steps To Reproduce:
1. Create some placeholders for views with createPlaceholderFolder() in perspective class
2. contribute a view to the perspective extension point (org.eclipse.ui.perspectiveExtensions) that has relationship set to stack and visible false. So no views should be visible in one of the placeholders at program start.
3. An empty placeholder is shown at application start for the placeholder that has no visible views at start
4. Activate a view that is placed in the currently empty placeholder 
5. View shows up in the empty placeholder, now close view
6. View and empty placeholder disappears
7. Open view again now placeholder and view appears. So after step 6 application works as expected which is that placeholder is not shown when no views are visible in it. So bug is only appearing at start of application.

This bug happens ONLY if relationship for view is set to stack. If you use left, right, bottom, top the emtpy placeholder is not shown and application works as expected.


More information:
The perspective class used when bug was found:

public class DefaultPerspective implements IPerspectiveFactory {
	
	public static final String ID = Activator.PLUGIN_ID + ".perspectives.defaultPerspective";

	public void createInitialLayout(IPageLayout layout) {
		
		String editorArea = layout.getEditorArea();
		layout.setEditorAreaVisible(false);
		
		
		layout.createPlaceholderFolder("folderTop", IPageLayout.TOP, 0.15f, editorArea);	
		layout.createPlaceholderFolder("folderRight", IPageLayout.RIGHT, 0.85f, editorArea);		
		layout.createPlaceholderFolder("folderRight1", IPageLayout.RIGHT, 0.81f, editorArea);
		layout.createPlaceholderFolder("folderRight3", IPageLayout.BOTTOM, 0.5f, "folderRight1");
		layout.createPlaceholderFolder("folderRight2", IPageLayout.BOTTOM, 0.5f, "folderRight1");
		layout.createPlaceholderFolder("folderRight4", IPageLayout.BOTTOM, 0.5f, "folderRight3");
		layout.createPlaceholderFolder("folderLeft", IPageLayout.LEFT, 0.2f, editorArea);
		layout.createPlaceholderFolder("folderBottom", IPageLayout.BOTTOM, 0.5f, editorArea);
		
		layout.createPlaceholderFolder("folderMain", IPageLayout.LEFT, 0.5f,
				editorArea);
		layout.createPlaceholderFolder("folderMainBottom", IPageLayout.BOTTOM, 0.5f,
				"folderMain");
	}
	
}

The plugin.xml perspective extension point declarations for the views.

 <view
               id="views.testView1"
               relationship="stack"
               relative="folderMainBottom"
               visible="false">
         </view>
         <view
               id="views.testView2"
               relationship="stack"
               relative="folderMainBottom"
               visible="false">
         </view>
