Cascading select option fields and watchers in an edit form

Hello,

I have this problem.

I have cascading select option fields in an edit form. I have set watchers to watch any new selection in the select option fields. All works fine in a create form. But in an edit form, as the input fields are dynamically filled with the model values, each time a select is getting his value, it generates an update of the other select option fields.

That's because the watchers are active as soon as the component is loaded.

What could be nice is a way to differ the activation of the watchers, for example the input fields are filled with the values and only then the watchers are activated. Or another way could be to activate the watchers for only manuel changed and not changes by the code.

Is it possible to do that ? And how ?

Thanks for your help ;).
