Hi,

I decided to migrate my little RCP project to Eclipse 4... and ran into this question:

When exactly is the ACTIVE_PART available?

I have a handler (see below) with a @CanExecute annotation. The "part" is usually not null and everything I expect it to be. However, right after startup - the part is restored alright - "part" is null and therefore the menu is disabled. Once I click into the part, or on the tab (it is a PartStack), everything works as expected.

    @CanExecute
    boolean isVisible(@Named(IServiceConstants.ACTIVE_PART) MPart part)
    {
        return null != part && part.getObject() instanceof PortfolioPart
                        && ((PortfolioPart) part.getObject()).getFile() != null;
    }

I am using Kepler 4.3

This may well be us faking you out. The CSS styling for the active stack is stored in the model but it may be that we aren't activating a part on startup.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=329458 for more details.

BTW, I've flagged that defect for a(nother) look in Luna M3.
