Description
Setting subobjects cityN with the property Has page.

{{#subobject:city1
| Has page = Athens
}}
...
{{#subobject:city101
| Has page = Athens
}}
...
Query
Query 1
{{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}}
Here no sort is used, i.e. the results are sorted by their subobject name. The problem is that some of the property chain values are not displayed at all.
{{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]] [[Has page::Athens]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}}
Querying for the city directly it shows all property chain values.
