Providing a custom sorter for Project Explorer [message #332895]

I'm trying to add a simple sorter to the Package Explorer view which is
supposed to override the default Java package sorting. Looking at the
org.eclipse.ui.navigator.navigatorContent documentation there seem to be
no way to install a custom sorter without also defining a corresponding
content and label providers which is what I'm trying to avoid. The
documentation page for this EP has an example for a standalone sorter
defined outside of navigatorContent tag but this doesn't appear to work,
at least not in 3.4.1. There is IPipelinedTreeContentProvider which can
likely help to pass through the content obtained from the Java content
provider as, however there seem to be no mechanism to pipeline label
providers so my label provider would have to somehow mimic what the Java
one is doing. Any suggestions on the simplest way to achieve this? Thanks
much.

Please file a bug about this. We should allow you to leave off the
content and labelprovider in your navigator content extension and only
define the sorter.

The pipeline stuff is not really what you are after since that has to do
only with chaining content providers together.

There is already an open enhancement request which seem to be about the
same issue, more or less anyway:
