Form value not displayed in Webinterface

OJS 3.3.0.11

We generate DOIs automatically and have implemented our own code for the plugin’s addPublicationFormFields function. At the end we add a form field like this, similar to the default “no pattern” variant:

$form->addField(new \PKP\components\forms\FieldText('pub-id::doi', [
	'label' => __('metadata.property.displayName.doi'),
	'description' => __('plugins.pubIds.doi.manager.settings.doiSuffixRandomIdentifier'),
	'value' => $generatedDOI,
]));

But the value is not displayed in the interface, we end up with an empty line edit.

In the browser’s network tools I see that the server sends the data correctly. The pkp.registry.init Javascript Snippet contains:

"fields":[{"name":"pub-id::doi","component":"field-text","label":"DOI","description":"Mit dieser Option wird eine 8-stellige, zufallsgenerierte ID (bestehend aus Zahlen und Buchstaben) generiert.","groupId":"default","isRequired":false,"isMultilingual":false,"value":"10.34780\/s7e7-fdh6","inputType":"text","optIntoEdit":false,"optIntoEditLabel":"","size":"normal","prefix":""}

When I change the form’s id to something slightly different, the value gets displayed. For example:

$form->addField(new \PKP\components\forms\FieldText('pub-id::doi-variant', [

So it seems to me like the doi form element gets some special treatment, but I am unable to discern where exactly this behaviour is triggered.

I also tried the following:

$form->addField(new \PKP\components\forms\FieldText('pub-id::doi', [
	'label' => __('metadata.property.displayName.doi'),
	'description' => __('plugins.pubIds.doi.manager.settings.doiSuffixRandomIdentifier'),
	'prefix' => $prefix,
	'separator' => '/',
	'value' => $generatedSuffix
]));

But again, the value is not displayed, just the prefix as a read only part of the input field.

Can anyone point me in the right direction?
