All - It seems that the page table of contents (value:toc) hasn't worked for a while - the problem can be resolved by updating this method:
<value: 'toc' comment: 'Display the table of contents of the current structure.'>
^ self lookupStructure: aContext structure do: [ :structure | [ :html |
in: html painter
on: html ] ]
Instead of html painter, use self.
How would one go about making this update in Pier3 package?
