Description
Setting subobjects cityN with the property Has page.
Property declaration
{{#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.

Query 2
{{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in|sort=Has page}}
Here sort=Has page is used, in contradiction to the previous query, all property values are displayed.

Query 3
{{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in|sort=Has page|order=rand}}
Here sort=Has page and order = rand is used, again, some property values are missing.

Query 4
{{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|sort=Has page.Located in}}
Offtopic, here trying to use sort=Has page.Located in. While the property chain values are displayed correctly, the sorting doesn't work at all. Something else takes precedence, ruining the intended sort, turning it internally into sort=,Has page.Located in, sort=Has page,Has page.Located in or sort=Has page. Not sure about this, but something is fishy here. I know that up to SMW 3.1.6 the sort sort = <property1>.<property2>,<property> is turned internally into sort = <property>,<property1>.<property2>, ordering the property chains by length first; but here that it somehow ignores the second property chain part is very wierd.
