[Semediawiki-user] #ask query: result value disappears

[<zeh...@mo...>]

When I try an {{#ask}} query with table output format, I see requested property
values in the table cells as long as the property is not defined (no property
page exists). As soon as I create a property page the value isn't displayed
anymore in the table.

Om page XYZ
 This has invisible [[Property1::1| ]] and [[Property2::2| ].
 [[Category:ABC]]

 {{#ask:
  [[Category:ABC]] |
  ?Property1 |
  ?Property2 |
  format = table
 }}

I get the result table

          Property1   Property2
    XYZ       1           2


as long as the page Property:Property1 doesn't exist. If I create that page with
the content [[has type:number]] and refresh the query result the value for
Property1 is gone:

          Property1   Property2
    XYZ                   2


An example can be seen on the page http://ontoworld.org/wiki/AGAP000006
The value for property 'Ensembl CDS length' was initially shown but now has
disappeared after I created page
http://ontoworld.org/wiki/Property:Ensembl_CDS_length

Do I miss something or is that a bug?

Thanks,
Gu
