    <p>I am developing a website using spring/hibernate. I have a domain class 'Answer' as below,</p> <h2>Answer.java</h2> <pre><code>@Entity public class Answer { @OneToMany(fetch=FetchType.EAGER) @JoinTable(name="Answer_comment",joinColumns=@JoinColumn(name="ANSWER_ID"), inverseJoinColumns=@JoinColumn(name="COMMENT_ID")) private Collection&lt;Comment&gt; comment; ------------------------------------- ------------------------------------- } </code></pre> <p>So I have One To Many relation among Answer and Comment entities. </p> <p>To test this I am using below code,</p> <pre><code>Answer commentAnswer = answerService.getAnswer(1001); Comment comment2 = new Comment(); comment2.setId(1004); comment2.setBody("I cannot agree with your answer..because ..."); comment2.setUser(userService.getUser("ss")); //commentService.create(comment2); Comment comment3 = new Comment(); comment3.setId(1005); comment3.setBody(" Yes I agree with your answer...sorry for my previous comment"); comment3.setUser(userService.getUser("ss")); //commentService.create(comment3); ArrayList&lt;Comment&gt; commentList = new ArrayList&lt;Comment&gt;(); commentList.add(comment2); commentList.add(comment3); commentAnswer.setComment(commentList); answerService.editAnswer(commentAnswer); </code></pre> <p>I am getting an existing Answer - 1001. And trying to add 2 comments newly created to that answer's comment collection. And saving that answer object.</p> <p>When I run this I am receiving the below error,</p> <pre><code> org.hibernate.LazyInitializationException: could not initialize proxy - no Session at the line -- commentAnswer.setComment(commentList); </code></pre> <p>Can someone please explain what am I doing wrong here?</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
