dependant field not working

There are 2 issues with the module:

• Error messages due to missing handler_settings index
• Ability to work with only one field on the entity edit form

Attaching the patch that hopefully fixes both ones. Please check!

d.novikov,
could you please explain me how can I apply the patch?
Currently I have the similiar issue
thanks

Hi guys!
I tested this attached patch and I can say that it works (for first look)
you can find patched module in attach
thanks to d.novikov

git apply (patch name)

The patch addresses the initial issue.
It allows the code to continue to a new error below.

1. Create a rule
2. Create a condition. This case the condition is comparing a field in an entity.
I saved the condition without completing it
3. I added the condition to the rule I created

I then get the error below.
there is a comparison at line 158 in business_rules/src/Plugin/BusinessRulesCondition/DataComparison.php:

 if ($data_to_compare == self::CURRENT_DATA) {
      $entity = $event->getArgument('entity');
    }
    elseif ($data_to_compare == self::ORIGINAL_DATA) {
      $entity = $event->getArgument('entity_original');
    }

there should be an option if "$date_to_compare" is NULL or empty. IE someone has not finished the rule.

I found that the field that I was using was defined but the data_to_compare was not.
field = field_my_address
data to compate =

When I saved content or did 'drush cr' I get:

Error: Call to a member function get() on null in drupal-8.4.4/html/modules/download/business_rules/src/Plugin/BusinessRulesCondition/DataComparison.php on line 164
#0 drupal-8.4.4/html/modules/download/business_rules/src/Entity/Condition.php(225): Drupal\business_rules\Plugin\BusinessRulesCondition\DataComparison->process(Object(Drupal\business_rules\Entity\Condition), Object(Drupal\business_rules\Events\BusinessRulesEvent))

Using this patch in a project and I can confirm that it works.

For me, patch #3 helps fixing the module, but I'm indeed still unable to work with more than one field on the entity edit form. (I'm using the dev version).

Any help would be welcome.

Fixed on version alpha11.

PluginBase in Drupal 8.5 does not bring the value of configuration['handler_settings'] as in previous version.

Did not worked on alpha15. Switched to dev version with patch #3.

I've made some mistake with GIT.
It's fixed on DEV now.

Thanks
