[news.eclipse.tools] M4 getInstance Not Working ?

[colin@xxxxxxxxxxxxxx (Colin)]

Maybe a stupid question, but is it somehow possible that the following
construction is not working anymore in M4 (When I test my plugin, when I
it's deployed there seems to be no problem) ? 

public class ResultView extends ViewPart
{
    private static ResultView instance = null;

    public static ResultView getInstance()
    {
        return instance;
    }

    public void createPartControl(Composite parent)
    {
        instance = this;
    }
}

The problem is that getInstance gives null. That was never the case. The
partcontrol is there, so how is it possible ?

Is this the way for other code to get the one and only instance of a view
anyway, or is there a prefered other way ?

Kind regards,

Colin.
