 Objet : Fw : Re: [xwiki-users] Question about Page type property (and an issue) in a

MyClass/Sheet/Template and in 
 another AnotherClass I add a Page type property with:
  - Display Type : select
 - XWiki Class Name: MyClass
 - Id Field Name: doc.fullName
 - Value Field Name : doc.name

 working well but ...
  
  I want that the user 
 select in my select
list: one page OR nothing.
  
 ...
