Description Davy Meers CLA 2010-08-09 05:55:50 EDT 
Build Identifier: 20100617-1415

In the PerspectiveFactory you can specify IPlaceHolderFolderLayout's with layout.createPlaceholderFolder.
Using the extension point "org.eclipse.ui.perspectiveExtensions" you can add views to a perspective.

It is possible to place a view relative to a IPlaceHolderFolderLayout (using the relative attribute), but you get the warning "Referenced identifier 'xxx' in attribute 'relative' cannot be found".

This is because of the extension point's schema, that expects an IDREF for the attribute "relative".

It would be nice if we could specify the IPlaceHolderFolderLayout's declaratively (or broader: extend the "org.eclipse.ui.perspective" extension point, so we don't need to create a perspectivefactory any longer).
This would also solve this bug.

Another option is to change the schema, so ithe relative attribute doesn't expect a ID. But i don't really like that, because it opens the door for typo's etcetera.

This is probably related to bug 287551 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=287551).

Reproducible: Always

Steps to Reproduce:
1.create a perspective and add a IPlaceHolderLayout
2.add a view to the perspective using the perspectiveExtensions extension point, relative to the created IPlaceHolderLayout
3.when you run the application everything works as expected, but you get the specified warning
