Bug 90257 [Preferences] Want to create an instanceof of a WorkingCopyManager
20050405 I'm currently referencing the internal class org.eclipse.ui.internal.preferences.WorkingCopyManager I have a base class that manages all the current settings and I changes that class to use the working copy manager. For the following reasons I also have to function when I don't get a working copy manager. To avoid complicated code it would be nice if in these case I could just use an internal instance of the working copy manager. - In the preference page, when testing if my container is really of kind IWorkbenchPreferenceContainer (so I can access the working copy manager) I have to also handle the case that the test returns false - We have some pages that are contributed by extension point that don't give me access to the container due to API limitations.

Key curr= fAllKeys[i];
			if (curr.getName().equals(key) && curr.getQualifier().equals(qualifier)) {
				selectOption(curr);
			}
		}
	}
	
	public void selectOption(Key key) {
		Control control= findControl(key);
		if (control != null) {
			if (!fExpandedComposites.isEmpty()) {
				ExpandableComposite expandable= getParentExpandableComposite(control);
				if (expandable != null) {
					for (int i= 0; i < fExpandedComposites.size(); i++) {
						ExpandableComposite curr= (ExpandableComposite) fExpandedComposites.get(i);
						curr.setExpanded(curr == expandable);
					}
					expandedStateChanged(expandable);
				}
			}
			control.setFocus();
		}
	}
