Good day, Let me show you a real magic! But I don't know the secret... If you know it - please describe me! It's real problem for me... 1 Class: | package xxx.finders; | | import org.jboss.seam.framework.EntityController; | import org.jboss.seam.log.Log; | import org.jboss.seam.annotations.Logger; | import org.jboss.seam.annotations.Transactional; | import xxx.Lecture; | | import java.util.List; | import java.util.ArrayList; | | public class AbstractFinder<K> | { | private String query; | | private List<K> result; | | | public final String getQuery() | { | return query; | } | | public final void setQuery(String query) | { | this.query = query; | } | | @Transactional | public void search() | { | System.out.println("start search. This:"+this); | this.result = searchResult(); | System.out.println("Cal result: "+result+" This:"+this); | } | | @Transactional | protected List<K> searchResult() | { | return new ArrayList<K>(); | } | | @Transactional | public final List<K> getResult() | { | System.out.println("Start getResult. this:"+this); | if(result==null) | { | System.out.println("searching"+this); | search(); | System.out.println("Cal result: "+result+" This:"+this); | } | System.out.println("result: "+result+"this:"+this); | return result; | } | } | 2 class | package xxx.finders; | | import xxx.testtree.Test; | | import java.util.List; | import java.util.ArrayList; | | import org.jboss.seam.annotations.Name; | import org.jboss.seam.annotations.Logger; | import org.jboss.seam.annotations.In; | import org.jboss.seam.annotations.Scope; | import org.jboss.seam.log.Log; | import org.jboss.seam.ScopeType; | | import javax.persistence.EntityManager; | | @Name("testFinder") | public class TestFinder extends AbstractFinder<Test> | { | @In | private EntityManager entityManager; | | @Logger | private Log log; | | protected List<Test> searchResult() | { | log.info("Invoked!!!"); | String query = getQuery(); | if(query==null || query.equals("")) | { | List<Test> tests = (List<Test>)entityManager.createQuery("select object(t) from Test t order by t.title").getResultList(); | log.info("Tests: "+tests); | return tests; | } | else | { | List<Test> ret = new ArrayList<Test>(); | String sql = "select object(t) from Test t where t.title like :query order by t.title"; | ret.addAll(entityManager.createQuery(sql).setParameter("query", "%"+query+"%").getResultList()); | sql = "select object(t) from Test t, Domain d where t.domain=d and d.title like :query order by t.title"; | ret.addAll(entityManager.createQuery(sql).setParameter("query", "%"+query+"%").getResultList()); | return ret; | } | } | } | Now the magic! Externaly from JSF page I'm trying to get result property from 'testfinder' bean. And there I recieve null! But look to the logs: | 2007-10-31 14:43:09,921 INFO [STDOUT] start search.
