    <p>I am using <a href="http://www.grails.org/plugin/nimble" rel="noreferrer">Nimble</a> and <a href="http://www.grails.org/plugin/shiro" rel="noreferrer">Shiro</a> for my security frameworks and I've just come accross a GORM bug. Indeed :</p> <pre><code>User.createCriteria().list { maxResults 10 } </code></pre> <p>returns <strong>10 users</strong> whereas <code>User.list(max: 10)</code> returns <strong>9 users</strong> ! </p> <p>After further investigations, I found out that <code>createCriteria</code> <strong>returns twice the same user</strong> (admin) <strong>because admin has 2 roles</strong>!!! (I am not joking).</p> <p>It appears that any user with more than 1 role will be returned twice in the <code>createCriteria</code> call and <code>User.list</code> will return <code>max-1</code> instances (i.e 9 users instead of 10 users) </p> <p><strong>What workaround can I use in order to have 10 unique users returned ?</strong></p> <p>This is a very annoying because I have no way to use pagination correctly. </p> <hr> <p>My domain classes are:</p> <pre><code>class UserBase { String username static belongsTo = [Role, Group] static hasMany = [roles: Role, groups: Group] static fetchMode = [roles: 'eager', groups: 'eager'] static mapping = { roles cache: true, cascade: 'none', cache usage: 'read-write', include: 'all' } } class User extends UserBase { static mapping = {cache: 'read-write'} } class Role { static hasMany = [users: UserBase, groups: Group] static belongsTo = [Group] static mapping = { cache usage: 'read-write', include: 'all' users cache: true groups cache: true } } </code></pre>

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.

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