Hi together,

we migrated a e3x app to e4, using compatibility layer. We have a licencing system which hides features from the user via activities, patterns, property tester.

And removing non-user perspectives from the Perspective Registry programmaticaly. This is broken....

Doe's anybody know a way to do that now?

The problem is this if:

public void deletePerspective(IPerspectiveDescriptor toDelete) {
PerspectiveDescriptor perspective = (PerspectiveDescriptor) toDelete;
if (perspective.isPredefined())
return;

descriptors.remove(perspective.getId());
removeSnippet(application, perspective.getId());
}

in the perspective Registry. Don't know why the heck this was done... Is it possible to manipulate the DI system in away your inhereited class is used?

I ended up using the XSLT transforms hook to remove/filter unwanted UI elements that activities could not hide, see:

Hello Erdal, your link is quite old, the CVS references from it are not available anymore.
In which file does the Transformer code belong?

You can consume the transforms hook from the main update site, for example, when using neon:

http://download.eclipse.org/releases/neon

Check the "Equinox Target Components"!
