Bug 20622 resize bug in "Override Method" [code manipulation]
When there's lot of methods potentially overrideable and I enlarge the override method view, the inner subfields do not enlarge accordingly. I enclose a screenshot that will make clear what I mean.

		fExpandedElements= elements;

				fCurrStatus= fValidator.validate(fViewer.getCheckedElements());
				updateStatus(fCurrStatus);

				fCurrStatus= new Status(IStatus.OK, PlatformUI.PLUGIN_ID, IStatus.OK, "", null);
