Problem with manually setting value

[andrzejdziekonski]

When i try to manually (javascript depending on some other user actions in my form view) set entity value in my view via:

[...]
$('.zenstruck-ajax-entity').select2('data',{id:foo, text:bar});

after saving from i get:
Warning: Illegal string offset 'id' in [...]/vendor/zenstruck/form-bundle/Zenstruck/Bundle/FormBundle/Form/Type/AjaxEntityType.php line 63

I found out it happens only when i trigger click event on 'Add' button (opening collection subform)

$('.form-collection-add').trigger('click');

then i set the value (as posted above) and after saving form i get the error.

I will look into this. Is there a zenstruck_ajax_entity form type in your subform?

[andrzejdziekonski]

Yes, of course. My declaration:

->add('example', 'zenstruck_ajax_entity', array(
                'placeholder' => '...',
                'label' => '...',
                'multiple' => false,
                'class' => 'MyBundle:Entity',
                'property' => 'title',
                'url' => $this->ajax_route,
                'required' => false))

setting it up works like a charm but there must be some major difference between triggering click action on 'Add' button and just clicking it (in this usual way everything is fine).

To make my problem 100% clear. I got some selectable component and depending on selects (multiple) i 'open' desired amount of collection subforms and fill it with data. So i:

1. trigger click action on '.form-collection-add' btn

$('.form-collection-add').trigger('click');

1. fill subform fields with my custom data (including passing id+text to select2 components)

//after passing other values to subform
$('#formId .zenstruck-ajax-entity').select2('data',{id:foo, text:bar});

Everything looks OK (filling subforms with data), selected entity on select2 looks like i did it on my own but saving form fails. Do u got any suggestions?

I am going to try and re-create.

[kbond]

Hmm, I just tried re-creating your issue and couldn't.

My recreation is here: https://github.com/kbond/sandbox/tree/form-34

I have an Article entity that can have one or more Link entity's. The Link entity has an zenstruck_ajax_entity for an Author entity.

What I tested:

1. When editing an Article, for the the "Links" subform, I clicked "Add"
2. In the chrome console, I entered $('#s2id_sandbox_appbundle_articletype_links_2_author').select2('data', { id: 1, text: 'Kevin' }) (An Author exists with id=1, name=kevin
3. The select2 updated correctly
4. Click "Save"
5. Success

Could you in step 1. do: $('#YourFormId .form-collection-add).trigger('click') ? When manualy i click 'Add' there is no problem for me as well. The thing i want to achieve is opening subform via javascript

[kbond]

Ok, I tried that but it still worked as expected.

Could you do a var_dump of $view->vars['value'] on the first line of this function: https://github.com/kbond/ZenstruckFormBundle/blob/master/Form/Type/AjaxEntityType.php#L47
