    <p>I'm trying to setup audit for our project. I started from the default configuration which works fine.</p> <p>The next step is to store the user which has made changes. Following the manual I created custom entity revision:</p> <pre><code>package com.csbi.samples.utils.audit; import java.io.Serializable; import java.text.DateFormat; import java.util.Date; import org.hibernate.envers.RevisionNumber; import org.hibernate.envers.RevisionTimestamp; import org.hibernate.envers.RevisionEntity; import javax.persistence.Id; import javax.persistence.GeneratedValue; import javax.persistence.Entity; import javax.persistence.Table; import javax.persistence.Transient; @Entity @Table(name="REVISIONS") @RevisionEntity(CustomRevisionListener.class) public class CustomRevisionEntity implements Serializable { private static final long serialVersionUID = -1255842407304508513L; @Id @GeneratedValue @RevisionNumber private int id; @RevisionTimestamp private long timestamp; private String username; public int getId() { return id; } public void setId(int id) { this.id = id; } @Transient public Date getRevisionDate() { return new Date(timestamp); } public long getTimestamp() { return timestamp; } public void setTimestamp(long timestamp) { this.timestamp = timestamp; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public boolean equals(Object o) { if(this == o) return true; if(!(o instanceof CustomRevisionEntity)) return false; CustomRevisionEntity that = (CustomRevisionEntity) o; if(id != that.id) return false; if(timestamp != that.timestamp) return false; if(timestamp != that.timestamp) return false; if(username != that.username) return false; return true; } public int hashCode() { int result; result = id; result = 31 * result + (int) (timestamp ^ (timestamp &gt;&gt;&gt; 32)); return result; } public String toString() { return "DefaultRevisionEntity(user = " + username + "id = " + id + ", revisionDate = " + DateFormat.getDateTimeInstance().format(getRevisionDate()) + ")"; } </code></pre> <p>}</p> <p>And also custom listener:</p> <pre><code>package com.csbi.samples.audit; import org.hibernate.envers.RevisionListener; public class CustomRevisionListener implements RevisionListener { public void newRevision(Object revisionEntity) { CustomRevisionEntity revision = (CustomRevisionEntity) revisionEntity; revision.setUsername("username"); //for testing } } </code></pre> <p>Here is some lines from log:</p> <blockquote> <p>DEBUG: org.hibernate.envers.configuration.metadata.AuditMetadataGenerator - Generating first-pass auditing mapping for entity com.csbi.samples.domain.Property.<br> DEBUG: org.hibernate.envers.configuration.metadata.AuditMetadataGenerator - Generating second-pass auditing mapping for entity com.csbi.samples.domain.Property.<br> INFO : org.hibernate.cfg.HbmBinder - Mapping class: com.csbi.samples.domain.Property_AUD -> PROPERTIES_AUD<br> INFO : org.hibernate.cfg.HbmBinder - Mapping class: org.hibernate.envers.DefaultRevisionEntity -> REVINFO</p> </blockquote> <p>Take a look at the last line of the output. There is still <code>DefaultRevisionEntity</code> mapped instead of <code>CustomRevisionEntity</code>.</p> <p>I have no idea what is wrong. Any suggestions? </p>

    2. COuse static variable for injection if you use spring or service factory if you use seam. https://209.132.182.48/message/641790. Hope that helps.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
