Method Details

build

public <E,
V extends View<?>> DialogWindow<V> build(LookupWindowBuilder<E,V> builder)

findContainer

@Nullable
protected <E> CollectionContainer<E> findContainer(LookupWindowBuilder<E,?> builder)

Specified by:

inferViewClass in class AbstractWindowBuilderProcessor

handleSelectionWithContainer

protected <E> void handleSelectionWithContainer(LookupWindowBuilder<E,?> builder,
 CollectionContainer<E> collectionDc,
 Collection<E> itemsFromLookup)

handleSelectionWithField

protected <E,
V extends View<?>> void handleSelectionWithField(LookupWindowBuilder<E,V> builder,
 com.vaadin.flow.component.HasValue field,
 Collection<E> itemsFromLookup)

transform

protected <E> Collection<E> transform(LookupWindowBuilder<E,?> builder,
 Collection<E> selectedItems)

getFetchPlanForField

@Nullable
protected FetchPlan getFetchPlanForField(com.vaadin.flow.component.HasValue<?,?> field)

The method evaluates the fetch plan that is used for the entity in the given field

If the value for a component (e.g. EntityPicker) is selected from lookup view then there may be cases when in entities in lookup view some attributes required in the detail are not loaded.

Returns:

a view or null if the fetch plan cannot be evaluated

 boolean initializeMasterReference,
 @Nullable
 MetaProperty inverseMetaProperty)

See getFetchPlanForField(HasValue) javadoc.

Returns:

a fetch plan or null if the fetch plan cannot be evaluated

reloadItemsByFetchPlan

protected <E> Collection<E> reloadItemsByFetchPlan(FetchPlan fetchPlan,
 Collection<E> itemsFromLookup)

toCollection

protected <E> Collection<E> toCollection(Object value,
 boolean isCollectionValue)

fromCollection

protected <E> Object fromCollection(Collection<E> value,
 boolean isCollectionValue)

updateFieldOptions

public <E> void updateFieldOptions(SupportsDataProvider<E> field,
 Collection<E> items)

Updates entities in options if they contain selected item from lookup view.
