How do you implement the logic of adding/updating multicategories in Yii2?

Question

Yii

Before version 2.0.8, I implemented additional getter and setter. properties.
The getter gets the selected categories, while the setter simply sets the value. Example #issuecomment-44921519
With this case, I used eachValidator with the integer rule, but in version 2.0.8 it swears that catIds should be an integer, I didn’t get into the code, I didn’t look at what they changed there.
For myself, I see the following solutions:
1) Remove getters and setters, make the catIds public property and fill it in the afterFind() method
2) Apply the intval filter to eachValidator (have not tried it yet)
3) Roll back to version 2.0.7 :)
And how you implement such logic? Maybe there are nice solutions?

recommended it to me for working with many-to-many connections. Before that, I used a public property and afterFind(), afterSave(), etc.
