Removing header from the Manifest

[alshamams]

I was trying to implement #864 and want to remove the existing header Eclipse-BundleShape in response to selection of default shape mode. This is what I am using:

Map<String, IManifestHeader> headers = ((Bundle) bundle).getHeaders();
Object entry = headers.remove(ICoreConstants.ECLIPSE_BUNDLE_SHAPE);
IBundleModel model = bundle.getModel();
model.fireModelChanged( new ModelChangedEvent(model, IModelChangedEvent.REMOVE, new Object[] { entry }, null));

For some reason, this doesn't seem to work. I can confirm that the header is indeed removed from the model by printing the current list of headers but the UI is not reflecting that - the Manifest Editor continues to display the removed header.
Any ideas?

@alshamams sadly this is quite cumbersome to manipulate the model, the best is to look how the manifest editor do it e.g. if you change the Bundle name or version.

somewhat related: https://bugs.eclipse.org/bugs/show_bug.cgi?id=411552 but still doesn't have a solution. Apart from the above recommendation, I suggest you debug model.fireModelChanged and see if it successfully completes or falls back due to some conditions and see what is missing.
