Hello all,
I’m working on implementing a new org.xwiki.model.reference.SpaceReference displayer for WikiMacro parameters.
The goal is to be able to easily set the value of wikimacro parameters expecting a space, using a dedicated picker.
Also, as there are no generic space picker, I’m also working on implementing one for this.
I created a jira ticket about it
I also started to create a design page for it.
If you have any feedback about it, I’d be glad to hear it 
Note that from a user perspective, I don’t think we should ask them to select a space since we only talk about pages and nested pages. At the level of APIs/java it’s fine though.
Maybe you could reuse (or extend) the document picker but add an option in it to only allowing selecting non-terminal pages (if that doesn’t exist already)?
Any progress? 
Thanks!
Yes, I also think this is the right approach. The end user should select a nested page not a space (even if the underlying parameter has space in its name).
