fix: INV-1278 avoid getUri() on false when deleting typeless resources

[tikhanovichA]

Summary

• After a successful ontology delete, ResourceRepository built ResourceDeleted with $resourceType->getUri() even when getTypes() was empty (reset() → false).
• That threw after the resource was already removed, so the UI reported failure while a reload showed the class gone.
• Guard empty types and set an empty resourceType string instead.

Context

• New classes from createSubClass() only get rdfs:subClassOf, not rdf:type.
• Reproduced when deleting a class folder via the resource-selector tree (class delete incorrectly hit deleteResource).

Summary by CodeRabbit

• Bug Fixes
  • Improved resource deletion handling for resources without explicitly defined types.
  • Deletion events now record the resource type safely when type information is available.

How to test

• Activate a new tree view by adding next config into config/tao/client_lib_config_registry.conf.php
'layout/tree/loader' => array( 'treeProvider' => 'resource-selector' ),

📝 Walkthrough

Walkthrough

ResourceRepository::delete now handles missing or non-resource types safely and preserves deletion context values. The unit test captures ResourceDeleted and verifies its payload for a typeless resource.

Changes

Resource deletion handling

Layer / File(s)	Summary
Safe type resolution and deletion event validation core/resource/Repository/ResourceRepository.php, test/unit/core/resource/Repository/ResourceRepositoryTest.php	delete checks the first type before calling getUri() and uses an empty resource type when no resource object exists. Tests verify the resource URI, selected class, parent class, and empty resource type in the emitted event.
