Html produced by Iwpage and Iwpages templates - which simply run js - don't come from the server, and obviously is not exported into derived files, as ePub.
There's a need to integrate Iwpage and Iwpages action into ProofRead extension; from interface pont of view, it will be sufficient to add a parameter lang=....
to <pages /> tag, and to build a new tag <iwpage lang=..... /> to be used in place of tl|Iwpage.
Version: unspecified
Severity: enhancement
Thanks for taking the time to report this!
What are exact steps to reproduce the problem?
Is there any testcase, or can the problem be seen on a public wiki?
MediaWiki doesn't allows currently interwiki transclusion. So, it's not possible to add such feature currently on the server side. It'll be very easy to adapt the template to avoid the use of js when bug 4547 will be solved. So, no needs of a new tag.
This is either a duplicate of bug 4547 or it's a feature request for ProofreadPage. I'm going to close it as the former, but if someone would rather it be the latter (changing the Product/Component back to MediaWiki extensions/ProofreadPage) I don't care.
