[xwiki-users] Question about Page type property (and an issue) in a Class

Hello, I create 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 My purpose is to display a list of page (with MyClass object): this point is working well but ... I want that the user select in my select list: one page OR nothing. Do you have an idea, how can I do that? I found a issue too: my select list list all page (with MyClass object) ... even my Template with MyClass object who is hidden. Thxs. Pascal B (xWiki 6.4)
