Adding a custom renderer to different parts

Question

I would like some parts to use a different renderer. In some cases I would like to remove the Detach option when right clicking and this is a solution according to a comment on my question here.

I've been following this tutorial as to how this can be done.

I've created two classes. UndetachableStackRenderer and UndetachableStackRendererFactory.

If I add UndetachableStackRendererFactory to the plugin.xml it successfully removes the option to detach from ALL part stacks.

<property
    name="rendererFactoryUri"
    value="bundleclass://com.example.loc/com.example.loc.UndetachableStackRendererFactory">
</property>

I would instead like to change the renderer for one part stack. According to the tutorial I can add CUSTOM_RENDERER_URI to the Persisted State of the part stack.

Key:

CUSTOM_RENDERER_URI

Value:

bundleclass://com.example.loc/com.example.loc.UndetachableStackRenderer

I've tried this and it does nothing. If I enter an incorrect location it doesn't come up with any errors either so it seems as though CUSTOM_RENDERER_URI isn't being seen.

What could be the cause of this?

The tutorial seems to be wrong, at least for the current Eclipse release.

The key value is defined in IPresentationEngine.CUSTOM_RENDERER_KEY and has the value Custom Renderer

String CUSTOM_RENDERER_KEY = "Custom Renderer";

It is used in the getRenderer method of org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine
