TagField doesn't render in AssetAdmin

[andrewandante]

Trying to add a TagField to Image and get an empty dropdown and no ability to add new tags. I imagine that React is getting in the way - happy to take a crack at it but have no idea what direction to go in.

To reproduce:

class GalleryImageExtension extends DataExtension
{
    private static $many_many = [
        'GalleryImageTags' => GalleryImageTag::class,
    ];
}

class GalleryImageFormFactoryExtension extends Extension
{
    public function updateFormFields(FieldList $fields, $controller, $formName, $context)
    {
        $image = $context['Record'];
        $tagField = TagField::create(
            'GalleryImageTags',
            'Tags',
            GalleryImageTag::get(),
            $image->GalleryImageTags()
        );
        $fields->addFieldToTab('Editor.Details', $tagField);
    }
}

class GalleryImageTag extends DataObject
{
    private static $db = [
        'Title' => 'Varchar(50)',
    ];

    private static $belongs_many_many = [
        'GalleryImages' => Image::class,
    ];

    private static $table_name = 'GalleryImageTag';
}

Ah yes, someone needs to build a react tagfield. :) It'll be a nice major job for someone, but we will probably do it at some point before 5.x.

AFAICT there's no multi-select fields built in React at the moment - is there a method of adding a non-reacty field into the React CompositeField nicely?

For now I will use a TextField with a delimiter :)

We built tree multi select field. ;)

Absolutely not. ;P

We fixed this recently with #110

@robbieaverill Just tried to add a TagField to AssetAdmin and it errors - Attempted to update component t[AssetAdmin.EditForm] that has already been unmounted (or failed to mount).

Oh damn!
