    <p>I have some strange results of findAllByPropertyInList() and think this is a bug in grails. See [1], the result is not what I expect it to be and what other queries say. Could it be that some kind of JOIN blows up the result, than max-property is executed and afterwards DISTINCT decreases the number of results again?</p> <p>Or does this have to do with Hibernate not being able to use DISTINCT and pagination proerties in one query?</p> <p>thx Sebastian</p> <p>[1]</p> <pre><code>def criteria = Foo.createCriteria() def results = criteria.listDistinct() { ... } results.id.unique().size() ==&gt;34 results.topic.unique().size() // some of the topics are duplicate ==&gt;25 def more = Foo.findAll([max:20, offset:0]).size() ==&gt;20 def more = Foo.getAll(results.id).size() ==&gt;34 def more = Foo.findAllByTopicInList(results.topic, [max:20, offset:0]).size() ==&gt; 7 // expected 25 def more = Foo.findAllByIdInList(results.id, [max:20, offset:0]).size() ==&gt; 7 // expected 34 class Foo { String topic SubCategory subCategory List&lt;Article&gt; articles WritingStyle writingStyle SortedSet&lt;Keyword&gt; keywords = []as SortedSet SortedSet&lt;String&gt; linkTexts = []as SortedSet ArticleType articleType = ArticleType.FreestyleArticle static belongsTo = [project: Project] static hasMany = [articles:Article, keywords: Keyword, linkTexts: String] static constraints = { topic(blank: false, size: 1..200) subCategory(nullable: false) writingStyle(nullable: true) articles nullable:true } static mapping = { writingStyle fetch: 'join' subCategory fetch: 'join' keywords cascade: 'all-delete-orphan' keywords fetch: 'join' linkTexts cascade: 'all-delete-orphan' } } </code></pre>

    1. COI would expect the last two results to be 20, because you set the max param. Without the max, I would expect 34 in both cases.

    2. COprobably you have associations in your domain model. Can you show us Foo? I guess you have defined to `fetch` those eager and not lazy. This will result in having one result item per association.

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.
