Chris75 Thank you for the answer. I can create pages using templates and Bureaucracy and I can use the value aggregation notation from struct. What doesn't work is reading data from the global schema.
Global schema has the two columns described above (website, address) with the two rows mentioned there.
The template is:
The address of @@web.website@@ is {{$web.address ? filter: "website = web.website"}}
I use this Bureaucracy form:
<form>
action template templates:webTPL "users:@NAME@:web"
struct_field "web.website"
submit "Create page"
</form>
When I enter the value "dokuwiki" it's passed to the template but the page created is:
The address of dokuwiki is {{$web.address ? filter: "website = web.website"}}
The value notation isn't parsed.
