Hi,

to reproduce the problem do the following:
- Generate simple RCP application (Hello RCP template).
- Add 3 views (View1, View2, View3), allowMultiple is set to true for each of them.
- Modify the perspective factory like this:

	public void createInitialLayout(final IPageLayout layout) {
		layout.setEditorAreaVisible(false);
		
		layout.addStandaloneViewPlaceholder(View1.ID + ":*", IPageLayout.BOTTOM, 0.0f, layout.getEditorArea(), true);
		layout.addStandaloneViewPlaceholder(View2.ID + ":*", IPageLayout.BOTTOM, 0.5f, View1.ID, true);
		layout.addStandaloneViewPlaceholder(View3.ID + ":*", IPageLayout.RIGHT, 0.5f, View2.ID, true);
	}

- Override the postWindowOpen() method in the ApplicationWorkbenchWindowAdvisor class:

	@Override
	public void postWindowOpen() {
		final IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
		try {
			page.showView(View1.ID, "secondaryId1", IWorkbenchPage.VIEW_CREATE);
			page.showView(View2.ID, "secondaryId2", IWorkbenchPage.VIEW_CREATE);
			page.showView(View3.ID, "secondaryId3", IWorkbenchPage.VIEW_CREATE);
		} catch (PartInitException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

- Run the application.

I expected this:

.-----------.
|   View1   |
|-----------|
|View2|View3|
'-----------'

But I got this:

.-----------.
|View3|View2|
|-----------|
|           |
|   View1   |
|           |
'-----------'

Even more interesting that it does not matter whether I put IPageLayout.RIGHT or IPageLayout.LEFT into the third placeholder line, I always get the above layout.

Target platform: 3.6 (20100617-1415)
OS: Ubuntu 10.04

Please let me know whether I misunderstood something or this is a bug.

Thanks,
Marton

I modified the perspective factory like this:

    public void createInitialLayout(final IPageLayout layout) {
        layout.setEditorAreaVisible(false);
        
        layout.addStandaloneViewPlaceholder(View1.ID + ":*", IPageLayout.BOTTOM, 0.0f, layout.getEditorArea(), true);
        layout.addStandaloneViewPlaceholder(View2.ID + ":*", IPageLayout.BOTTOM, 0.5f, View1.ID + ":*.standalonefolder", true);
        layout.addStandaloneViewPlaceholder(View3.ID + ":*", IPageLayout.RIGHT, 0.5f, View2.ID + ":*.standalonefolder", true);
    }

Now the layout appears properly.

The drawback of this solution is that the ".standalonefolder" is internal, there is not even a constant defined for it.
The API should be enhanced.
