Bug report

It seems that select2_from_ajax never calls the function to fetch data to the dropdown.

What I did

After upgrading Backpack from version 3.6 to 5 (PRO), we have noticed that select2_from_ajax doesn’t work. From debugging, it is apparent that the function bpFieldInitSelect2FromAjaxElement() is never called, and therefore there are never any data returned from any API endpoints.

We had this configuration: $this->crud->addField([ 'label' => 'Mærke', 'name' => 'brand_id', 'type' => 'select2_from_ajax', 'entity' => 'brand', 'attribute' => 'name', 'model' => Brand::class, 'data_source' => url('api/brands/all'), 'placeholder' => 'Select a car brand', 'minimum_input_length' => 0, 'method' => 'POST', 'attributes' => $this->disabledAttributes(), 'tab' => self::TAB_1, ]);

What I expected to happen

I expected it would call the function and thereby the API endpoint.

What happened

The API endpoint was never called.

What I’ve already tried to fix it

I don’t believe it’s a thing I should fix since it’s a bug in Laravel Backpack.

Is it a bug in the latest version of Backpack?

Yes

After I run composer update backpack/crud the bug… is it still there? Yes
