| I tried:
{{groovy}}
services.query.xwql("select space.reference from Space space where space.reference not in (select d.fullName from Document d)").execute()
{{/groovy}}
I expected the query to run fine (I guess I'm supposed to get a list of spaces without a corresponding document; this is a MWE, this may not actually be accurate or even useful). Instead, I got:
Failed to execute the [groovy] macro. Cause: [Document is not mapped]. Click on this message for details.

More precisely, the query seems to be translated to the following HQL:
select space.reference from com.xpn.xwiki.doc.XWikiSpace as space where space.reference not in ( select d.fullName from Document d )
what is between the NOT IN parentheses is surprising, Document should have been translated to XWIkiDocument. This part of the query seems to be output as is instead of translated. |
