ORDER condition not working in cakephp 3 TREE behavior - cakephp-3.0

Question

I am using cakephp-3 tree behavior for Categories table. Here 'sequence_no' field are using to sorting sub-category list for a category. I am searching with a category_id to get all of his child category in ASCENDING order by 'sequence_no'. But order not working here. My code snippet and output here.
$categoris = $this->Categories->find('children', ['for' => $id])
->find('threaded')
->contain('ParentCategories')
->order(['Categories.sequence_no' => 'ASC'])
->toArray();

Answer 1

Since findChildred finder add a ORDER lft asc clause to your query your order conditions will be appended to that
If you want to force your order you can do
->order(['Categories.sequence_no' => 'ASC'], true)
the second parameter in the order() method tells cake to overwrite the ORDER BY set before
see the manual, about the end of this paragraph
