Bug 242225 [Viewers] EditingSupport#setValue() doc
It would be nice if the Javadoc of org.eclipse.jface.viewers.EditingSupport#setValue(Object element, Object value) could mention that it is necessary to call this in order to show the new updated value: getViewer().update(row, null);
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/EditingSupport.java
private ColumnViewer viewer;
	/**
	 * @param viewer
	 *            a new viewer
	 */
	public EditingSupport(ColumnViewer viewer) {
		Assert.isNotNull(viewer, "Viewer is not allowed to be null"); 
		this.viewer = viewer;
	}
	/**
	 * The editor to be shown
	 *
	 * @param element
	 *            the model element
	 * @return the CellEditor
	 */
	protected abstract CellEditor getCellEditor(Object element);
	/**
	 * Is the cell editable
	 *
	 * @param element
	 *            the model element
