Matous Jobanek created JBIDE-19015: -------------------------------------- Summary: JPA Hibernate validator cannot work with the annotation @ElementCollection Key: JBIDE-19015 URL: https://issues.jboss.org/browse/JBIDE-19015 Project: Tools (JBoss Tools) Issue Type: Bug Components: hibernate Environment: JBDS 8.0.1.GA Reporter: Matous Jobanek The JPA Hibernate cannot work with variables annotated with the annotation @ElementCollection. When this annotation is used and for example the annotation @ManyToOne is used as well, the JBDS shows errors at places where they shouldn't be. Follow my instructions to reproduce this issue: 1. Download attached reproducer ui-ejb-minimized.zip 2. Extract it 3. Import the project into JBDS as an existing maven project 4. Look at the errors. There are two errors for this project: {noformat} Target entity is not defined Person.java /ui-ejb-minimized/src/main/java/org/jboss/seam/example/ui line 25 JPA Problem The given name of the entity "org.jboss.seam.example.ui.Country" is empty Country.java /ui-ejb-minimized/src/main/java/org/jboss/seam/example/ui line 9 JPA Problem {noformat} Both of them are unnecessary because both the target entity and the name of the entity are optional. 5. Comment the variable: {code} @ElementCollection private List<String> notes = new ArrayList<String>(); {code} 6. Save the class Person 7. Click on Project -> Clean Then all the errors will disappear. 8. uncomment the variable with the annotation back 9. Save the class Person 10. Click on Project -> Clean The two errors are back The attached reproducer is minimized Seam project ui-ejb of the example ui. https://github.com/seam2/jboss-seam/tree/Seam_2_3/examples/ui This Seam example is more complicated and the number of the wrong errors shown in JBDS is much bigger. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
