[xwiki-users] Database List Class

Hi All, i want use database list class as property in my class. I tried hibernate query to fill in values of property. After this, the select box was empty. I think there is no problem in query (Select doc from XWikiDocument as doc) and I filled in value (doc.name) and id (doc.id) and also i filled in which class should hibernate use. (XWikiDocument). I dont know, what I am doing wrong. Is there some tutorial for this? There is values which i filled in Display type : select Relational Storage: yes Use Picker: yes Size : 1 Sort: value Hibernate Query:select doc from XWikiDocument as doc XWiki Class Name: XWikiDocument Id Field Name: doc.name Value Field Name: doc.name Thank you.
