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);

	protected abstract boolean canEdit(Object element);
	/**
	 * Get the value to set to the editor
	 *
	 * @param element
	 *            the model element
	 * @return the value shown
	 */
	protected abstract Object getValue(Object element);
	/**
	 * Restore the value from the CellEditor

	 *            the model element
	 * @param value
	 *            the new value
	 */
	protected abstract void setValue(Object element, Object value);
	/**
