Setting targetElement param in @IndexedEmbedded on collection causes runtime exception -------------------------------------------------------------------------------------- Key: HSEARCH-1111 URL: https://hibernate.onjira.com/browse/HSEARCH-1111 Project: Hibernate Search Issue Type: Bug Components: mapping Affects Versions: 3.4.2 Environment: Hibernate 3.6.10, mysql 5.1 Reporter: Elmer van Chastelet Attachments: embeddedTestWithAdditionalTargetClassField.diff When I have an @IndexedEmbedded field with the targetElement set to a subclass of the embedded type (at least the case for a collection), indexing goes wrong. After seeing this behavior in my own app, I extended src/test/java/org/hibernate/search/test/embedded/AbstractProduct to have a pricingFeatures field: {code:java} @ManyToMany(mappedBy="product", cascade=CascadeType.ALL) //just to make the test easier, cascade doesn't really make any business sense @IndexedEmbedded(targetElement=PricingFeature.class) private Set<ProductFeature> pricingFeatures = new HashSet<ProductFeature>(); {code} Added PricingFeature class: {code:java} package org.hibernate.search.test.embedded; import org.hibernate.search.annotations.Field; import org.hibernate.search.annotations.Index; public class PricingFeature extends ProductFeature { @Field(index= Index.UN_TOKENIZED) private String price; public String getPrice() { return price; } public void setPrice(String price) { this.price = price; } } {code} The test itself {{org.hibernate.search.test.embedded.EmbeddedTest}} is untouched, and {{testEmbeddedToManyInSuperslass}} fails with the following exception: {code} EmbeddedTest org.hibernate.search.test.embedded.EmbeddedTest testEmbeddedToManyInSuperslass(org.hibernate.search.test.embedded.EmbeddedTest)
