The following call leads to an error in the demo: {{#!java TLModelUtil.resolveQualifiedName("tl5.enum:tl.beacon.three")

.tValueByName("annotations")

}}}

The cause is probably PersistentEnumeration.tValue(TLStructuredTypePart). There PersistentObjectImpl.getValue(this, part) is called. This ultimately leads to PrimitiveStorage.getAttributeValue(TLObject, TLStructuredTypePart). There, for the case attribute.isMultiple(), the storageValue is cast to String unchecked, but is a Config interface(PersistentModelPart$AnnotationConfigs).

Possibly the problem affects other classes and methods of the persistent model.

Noticed in the inspector: In the administration inspect the table of TLEnumerations. There tableData -> tableModel -> inner -> expand rows. Expanding rows fails and this error message appears in the log.
