[xwiki-users] XWiki Application: Pages of one app as dropdown values of other app

Hi community, I implemented a customer profile holding information about customers as an XWiki application. Now in another app I'd like to have an optional field that can contain the customer if it is related to one. Therefor I want to list all customers (existing pages of App 1) as dropdown values of a field of App 2. To illustrate what I'd like to achieve: App 1 (holding customer information): |-- Page "Customer 1" |-- Page "Customer 2" ... App 2 (holding other information but can be customer related): |-- Page 1 |-- Field "Customer" = Dropdown of Pages of App 1 (Customer 1, Customer 2 ...) I'm rather new in scripting in XWiki/Velocity so I'd really appreciate some help on this :) Regards, Dennis
