name: Jmix Soft Deletion description: Work with soft-deleted entities in Jmix applications. Use this skill when implementing features that need to show or hide soft-deleted records. Use this skill when bypassing soft deletion filtering to include deleted entities in queries. Use this skill when working with @DeletedDate and @DeletedBy annotations. Use this skill when implementing "show deleted" toggles in list views.

Jmix Soft Deletion

When to use this skill

• When implementing a toggle to show/hide soft-deleted entities in a view
• When writing queries that need to include soft-deleted records
• When using LoadContext hints to control soft deletion filtering
• When working with entities that have @DeletedDate and @DeletedBy annotations
• When implementing restore functionality for soft-deleted entities

Instructions

Entity Setup

Entities with soft delete support have these annotations:

Copy@DeletedBy
@Column(name = "DELETED_BY")
private String deletedBy;

@DeletedDate
@Column(name = "DELETED_DATE")
private OffsetDateTime deletedDate;

Including Soft-Deleted Entities in Queries

Use PersistenceHints.SOFT_DELETION with a LoadContext or loadDelegate:

Copyimport io.jmix.data.PersistenceHints;  // IMPORTANT: NOT io.jmix.core

@Install(to = "entityDl", target = Target.DATA_LOADER)
private List<Entity> loadDelegate(LoadContext<Entity> loadContext) {
    boolean showDeleted = Boolean.TRUE.equals(showDeletedCheckbox.getValue());
    loadContext.setHint(PersistenceHints.SOFT_DELETION, !showDeleted);
    return dataManager.loadList(loadContext);
}

• SOFT_DELETION = true (default): Filters out deleted entities
• SOFT_DELETION = false: Includes deleted entities

Important Considerations

1. Caching: Remove cacheable="true" from XML loaders when dynamically toggling soft deletion, as cached results may ignore hint changes.

2. Reload on toggle: When the user toggles the show/hide deleted checkbox, call loader.load() to refresh the data:

Copy@Subscribe("showDeletedCheckbox")
public void onShowDeletedCheckboxChange(AbstractField.ComponentValueChangeEvent<JmixCheckbox, Boolean> event) {
    entityDl.load();
}

1. Visual distinction: Combine with vaadin-grid-styling skill to visually distinguish deleted entities (e.g., faded/gray appearance).
