Description

After the enhanced multi column layout has been chosen, enhanced 3 column and 2 column layouts. If no changes are made on the page and if save and apply is done if gives an exception. The same exception happens for all users that are logged in. The problem might have arisen from either a NPE with no moves selected or an array out of bounds issue.
