The user can create quite a complex query based on (almost) random selection of query criteria. I have everything working, query does what it should do and finds the correct resulting objects. Then these are displayed with a standard D2WListPage. The customer wants the displayPropertyKeys to reflect the query criteria. There are way too many combinations so I cannot just have a couple of rule based ready-made displayPropertyKey arrays. So my idea was to build the array dynamically inside the custom property level component, because that is the only place where I know exactly what properties should be in the resulting list page. Of course I could create my own custom ListPage and build the list in code, but I always think D2W and the computer are being "payed" to work thus they should do the work, not me!
