Hi,

Trying to apply drag and drop sort ordering to a site.

We have Products (DataObject) which have a many_many relationship with CategoryPage(Page types).

The relationship works fine, apart from sort ordering. We have used the directive:

SortableDataObject::add_sortable_many_many_relation('CategoryPage','Products');

To try and add drag and drop sort ordering to the categoryPage administration, so the end user can reorder products in a category.

When we add the directive to the _config.php, a dev/build shows that the sort order column has been created, but there are no changes in the admin. It appears that the directive is being ignored.

Any ideas guys?

Look closely at the argument signature for that function. The first parameter is the class where many_many is defined, and the second is the name of the many_many relation.
