The RDF UI & RDF UI Builder modules doesn't work in Drupal 8.1.2 Core

Hi @matio89,
I could not produce the errors you mentioned. Please share the error logs (possibly with backtrace info) if you can.

core 8.1.7
+
rdfui 8.x-1.0-beta1

Seemed to provide the autocomplete and manage RDF page OK.
Changes seemed to stick, and pages rendered with my attached schema metadata.

Though I did get other errors, such as

drush cr
PHP Fatal error:  Cannot use Drupal\Component\Utility\String as String because 'String' is a special class name in /private/var/www/drupal8.1/docroot/modules/contrib/rdfui/src/Form/FieldMappings.php on line 11

(against PHP 5.5.30, Drush 8.1.3. I tried against php7, just in case, but got the same)

Updating to rdfui-8.x-1.x-dev
did produce the error results described by matio89 :
No autocomplete on either the RDF tab on /admin/structure/types/manage/* or /admin/structure/types/manage*/fields/rdf
In fact my previously working predicates there seem to be lost.

I got no error log (watchdog, PHP or to-screen), though there was a single javascript console error on that page, not sure if it's related.

jquery.js:5562 GET http://drupal81.dd:8083/modules/core/assets/vendor/jquery.ui/themes/base/images/ui-bg_flat_75_ffffff_40x100.png 404 (Not Found)

Please try the latest development version at https://www.drupal.org/project/rdfui/releases/8.x-1.x-dev
If the problem persists, please reopen this issue.
Thanks for reporting.

Hi, I'm running Drupal 8.9.13.
When I run composer require drupal/rdfui , it installs automatically drupal/rdfui (1.0.0-beta3)
So I run composer require drupal/rdfui ^1.0.0-beta4 and I get the following error :

Your requirements could not be resolved to an installable set of packages.

With beta3, It throws an error when I enable the RDF UI module.

I tried with dev :

composer require 'drupal/rdfui:1.x-dev@dev'
./composer.json has been updated
