Transclusion is only allowed from projectdoc documents. Confluence pages without the Document Properties Marker Macro usually do not work.

Summary

 

Transclusion only works with plain Confluence pages since version 1.11 of the projectdoc Toolbox.

Before that version only transclusion from projectdoc documents was defined. Creating a projectdoc document is simple: add the Document Properties Marker Macro. No special properties required.
